Validation of the International Trauma Questionnaire-Child and Adolescent Version (ITQ-CA) in a Chinese mental health service seeking adolescent sample

BACKGROUND

The International Trauma Questionnaire-Child and Adolescent version (ITQ-CA) is a self-report measure that assesses posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on the diagnostic formulation of the 11th version of the International Classification of Diseases (ICD-11). This study aimed to provide a Chinese translation and psychometric evaluation of the ITQ-CA using a sample of mental-health service seeking adolescents in Mainland China.

METHODS

The ITQ-CA was translated and back-translated from English to simplified Chinese and finalized with consensus from an expert panel. Adolescents ages 12-17 were recruited via convenience sampling from an outpatient psychiatric clinic in Mainland China. Participants completed the ITQ-CA; measures of four criterion variables (depression, anxiety, stress, adverse childhood experiences); and the PTSD Checklist for DSM-5 (PCL-5). Construct validity, concurrent validity, and comparison of PTSD caseness between ICD-11 and DSM-5 measures were assessed.

RESULTS

The final sample consisted of 111 Chinese adolescents (78% female; mean age of 15.23), all diagnosed with a major depressive disorder. Confirmatory factor analysis indicated the two-factor second-order model provided optimal fit. All criterion variables were positively and significant correlated with the six ITQ-CA symptom cluster summed scores. In the present sample, 69 participants (62.16%) met symptom criteria for ICD-PTSD or CPTSD using the ITQ-CA, and 73 participants (65.77%) met caseness for DSM-5 PTSD using the PCL-5. Rates of PTSD symptom cluster endorsement and caseness deriving from both diagnostic systems were comparable.

CONCLUSIONS

The Chinese ITQ-CA has acceptable psychometric properties and confers additional benefits in identifying complex presentations of trauma-related responses in younger people seeking mental health services.

The International Trauma Questionnaire: development of a self-report measure of ICD-11 PTSD and complex PTSD

OBJECTIVE

The purpose of this study was to finalize the development of the International Trauma Questionnaire (ITQ), a self-report diagnostic measure of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD), as defined in the 11th version of the International Classification of Diseases (ICD-11).

METHOD

The optimal symptom indicators of PTSD and CPTSD were identified by applying item response theory (IRT) analysis to data from a trauma-exposed community sample (n = 1051) and a trauma-exposed clinical sample (n = 247) from the United Kingdom. The validity of the optimized 12-item ITQ was assessed with confirmatory factor analyses. Diagnostic rates were estimated and compared to previous validation studies.

RESULTS

The latent structure of the 12-item, optimized ITQ was consistent with prior findings, and diagnostic rates of PTSD and CPTSD were in line with previous estimates.

CONCLUSION

The ITQ is a brief, simply worded measure of the core features of PTSD and CPTSD. It is consistent with the organizing principles of the ICD-11 to maximize clinical utility and international applicability through a focus on a limited but central set of symptoms. The measure is freely available and can be found in the body of this paper.

Validation of post-traumatic stress disorder (PTSD) and complex PTSD using the International Trauma Questionnaire

OBJECTIVE

The 11th version of the International Classification of Diseases (ICD-11) has proposed two related trauma diagnoses: Post-traumatic stress disorder (PTSD) and Complex PTSD (CPTSD). Using a newly developed, disorder-specific measure of PTSD and CPTSD called the International Trauma Questionnaire (ITQ) the current study will (i) assess the factorial validity of ICD-11 PTSD and CPTSD; (ii) provide the first test of the discriminant validity of these constructs; and (iii) provide the first comparison of ICD-11, and Diagnostic and Statistical Manual, Fifth Edition (DSM-5), PTSD diagnostic rates using disorder-specific measures.

METHOD

ICD-11 and DSM-5 PTSD-specific measures were completed by a British clinical sample of trauma-exposed patients (N = 171). The structure and validity of ICD-11 PTSD and CPTSD were assessed by means of factor analysis and assessing relationships with criterion variables.

RESULTS

Diagnostic rates under ICD-11 were significantly lower than those under DSM-5. A two-factor second-order model reflecting the distinction between PTSD and CPTSD best represented the data from the ITQ; and the PTSD and CPTSD factors differentially predicted multiple psychological variables.

CONCLUSION

The factorial and discriminant validity of ICD-11 PTSD and CPTSD was supported, and ICD-11 produces fewer diagnostic cases than DSM-5.

Alternative models of disorders of traumatic stress based on the new ICD-11 proposals

OBJECTIVE

Although there is emerging evidence for the factorial validity of the distinction between post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) proposed in ICD-11, such evidence has been predominantly based on using selected items from individual scales that describe these factors. We have attempted to address this gap in the literature by testing a range of alternative models of disorders of traumatic stress using a broader range of symptoms and standardized measures.

METHOD

Participants in this cross-sectional study were a sample of individuals who were referred for psychological therapy to a National Health Service (NHS) trauma centre in Scotland (N = 195). Participants were recruited over a period of 18 months and completed measures of stressful life events, DSM-5 PTSD, emotion dysregulation, self-esteem and interpersonal difficulties.

RESULTS

Overall, results indicate that a structural model incorporating six first-order factors (re-experiencing, avoidance of traumatic reminders, sense of threat, affective dysregulation, negative self-concept and disturbances in relationships) and two second-order factors (PTSD and disturbances in self-organization [DSO]) was the best fitting. The model presented with good concurrent validity. Childhood trauma was found to be more strongly associated with DSO than with PTSD.

CONCLUSION

Our results are in support of the ICD-11 proposals for PTSD and CPTSD.

Preparedness for a major incident: creation of an epidemiology protocol for a health protection register in England

Large incidents and natural disasters are on the increase globally. They can have a major impact lasting many years or decades; and can affect large groups of people including those that are more susceptible to adverse consequences. Following a major incident, it may be considered necessary to establish a register of those people affected by the incident to provide appropriate advice on relevant immediate and longer-term public health interventions that may be required, provide reassurance to the public that their care is paramount, to reassure the worried well to avoid them inappropriately overwhelming local services, and to facilitate epidemiological investigations. Arrangements for the prompt follow-up of populations after large incidents or disasters have been agreed in England and a protocol for establishing a register of individuals potentially affected by a large incident has been developed. It is important for countries to have a protocol for implementing a health register if the circumstances require one to be in place, and are supported by Public Health Authorities. Health registers facilitate the initial descriptive epidemiology of exposure and provide the opportunity of carrying out long term analytical studies on the affected population. Such epidemiological studies provide a greater understanding of the impact that a large incident can have on health, which in turn helps in the planning of health care provision. Registers can also assist more directly in providing access to individuals in need of physical and mental health interventions. The challenge that still remains is to formally pilot the register in the field and refine it based on that experience.

Objective predictors of delayed-onset post-traumatic stress disorder occurring after military discharge

BACKGROUND

Post-traumatic stress disorder (PTSD) that develops after military personnel have been discharged may lead to severe impairment. We investigated whether personnel who develop PTSD after discharge can be identified by independent evidence of internalizing signs such as depression or of externalizing signs such as disciplinary offences while still serving.

METHOD

Veterans in receipt of a war pension who only developed PTSD post-discharge were compared with matched veterans who developed PTSD in service or never suffered from PTSD. Contemporaneous medical and personnel records were searched for objective evidence of internalizing and externalizing disorder.

RESULTS

Service personnel who developed PTSD post-discharge were indistinguishable from controls with no PTSD on their psychiatric presentation in service. Those with post-discharge PTSD had significantly more disciplinary offences, specifically absence without leave, disobedience, and dishonesty, than the no-PTSD group, and this excess of offences was present before any exposure to trauma.

CONCLUSIONS

This is the first study to find objective evidence independent of self-report for the claimed link between externalizing disorder and vulnerability to PTSD. Early signs of externalizing disorders may play an important role in helping to identify service personnel at risk of PTSD after military discharge.

Trauma, identity and mental health in UK military veterans

BACKGROUND

Military service can lead to profound changes in identity, both in servicemen's perception of themselves and in their relationship to the world, but the significance of these changes for psychopathology is unclear. We investigated whether the extent and valence of identity change was related to the degree of military trauma exposure or to post-traumatic stress disorder (PTSD) and suicide attempts. We further sought to describe the nature of such changes using qualitative analysis.

METHOD

A total of 153 veterans in receipt of a war pension for PTSD or physical disability were identified. Interviews established retrospectively DSM-IV diagnoses of PTSD and reports of suicidal ideation or behaviour since enlistment were examined.

RESULTS

Trauma exposure alone was unrelated to any measure of identity change. By contrast, PTSD was associated with a relationship to the world that had changed in a negative direction. It was also associated with a changed perception of self, which could be either positive or negative. After controlling for trauma exposure and PTSD, suicidal behaviours were associated with more negative perceptions of the world. These perceptions of the world included disillusionment about human nature and a more specific rejection of civilian life.

CONCLUSIONS

PTSD and suicidal behaviours in veterans seem not to be associated with significantly more negative views of the self but rather with more alienation from civilian life. This has serious consequences for engaging veterans in National Health Service (NHS) mental health services and for the provision of effective treatment.

Association between flashbacks and structural brain abnormalities in posttraumatic stress disorder

OBJECTIVE

Posttraumatic stress disorder (PTSD) is reliably associated with reduced brain volume relative to healthy controls, in areas similar to those found in depression. We investigated whether in a PTSD sample brain volumes in these areas were related to reporting specific symptoms of PTSD or to overall symptom severity.

METHOD

Structural MRI scans were obtained from 28 participants diagnosed with PTSD according to DSM-IV-TR. Participants reported the extent of individual PTSD symptoms using the Posttraumatic Diagnostic Scale. Voxel-based morphometry applying the Dartel algorithm implemented within SPM5 was used to identify volumetric changes, related to PTSD total, symptom cluster, and individual symptom scores.

RESULTS

Brain volume was unrelated to overall PTSD severity, but greater reexperiencing scores predicted reduced volumes in the middle temporal and inferior occipital cortices. Increased reports of flashbacks predicted reduced volume in the insula/parietal operculum and in the inferior temporal gyrus.

CONCLUSION

The data illustrate the value of analyses at the symptom level within a patient population to supplement group comparisons of patients and healthy controls. Areas identified were consistent with a neurobiological account of flashbacks implicating specific abnormalities in the ventral visual stream.

Outreach and screening following the 2005 London bombings: usage and outcomes

BACKGROUND

Little is known about how to remedy the unmet mental health needs associated with major terrorist attacks, or what outcomes are achievable with evidence-based treatment. This article reports the usage, diagnoses and outcomes associated with the 2-year Trauma Response Programme (TRP) for those affected by the 2005 London bombings.MethodFollowing a systematic and coordinated programme of outreach, the contact details of 910 people were obtained by the TRP. Of these, 596 completed a screening instrument that included the Trauma Screening Questionnaire (TSQ) and items assessing other negative responses. Those scoring ≥6 on the TSQ, or endorsing other negative responses, received a detailed clinical assessment. Individuals judged to need treatment (n=217) received trauma-focused cognitive-behaviour therapy (TF-CBT) or eye movement desensitization and reprocessing (EMDR). Symptom levels were assessed pre- and post-treatment with validated self-report measures of post-traumatic stress disorder (PTSD) and depression, and 66 were followed up at 1 year.

RESULTS

Case finding relied primarily on outreach rather than standard referral pathways such as primary care. The effect sizes achieved for treatment of DSM-IV PTSD exceeded those usually found in randomized controlled trials (RCTs) and gains were well maintained an average of 1 year later.

CONCLUSIONS

Outreach with screening, linked to the provision of evidence-based treatment, seems to be a viable method of identifying and meeting mental health needs following a terrorist attack. Given the failure of normal care pathways, it is a potentially important approach that merits further evaluation.

Pain flashbacks following the July 7th 2005 London bombings

Flashbacks in posttraumatic stress disorder (PTSD) are commonly experienced as visual, auditory, olfactory or tactile re-livings of a previously experienced traumatic event. We present the case report of one survivor of the July 7th 2005 London underground bombings who was diagnosed with PTSD and who experienced painful flashbacks. We present retrospective multidimensional measures of his pain using standardised instruments. The case provides further evidence that somatosensory re-experiencing of pain memories is possible. Findings are discussed with regards to memory for pain.

A comparison of flashbacks and ordinary autobiographical memories of trauma: cognitive resources and behavioural observations

We investigated predictions derived from the dual representation theory of posttraumatic stress disorder, which proposes that flashbacks and ordinary memories of traumas are supported by different types of representation. Sixty-two participants, meeting DSM-IV diagnostic criteria for posttraumatic stress disorder, completed a detailed written trauma narrative, and afterwards identified those sections in the narrative that had been written in flashback and ordinary memory periods. Performance on cognitive tasks confirmed predictions that flashback periods would be associated with a specific decrement in visuospatial processing. Contrary to prediction, periods of both flashback and ordinary memory were associated with decrements on a verbal processing task. Independent observer ratings also confirmed that flashback periods were associated with increases in a wide range of autonomic and motor behaviours.

Thought suppression, intelligence, and working memory capacity

The importance of individual differences in intelligence and working memory capacity in predicting the ability to intentionally suppress thoughts was investigated. Sixty participants completed a thought suppression task, and measures of working memory capacity (OSPAN), fluid intelligence (Raven's Matrices), and crystallised intelligence (the National Adult Reading Test). As predicted, the results indicated that more effective thought suppression was independently related to higher working memory capacity and greater fluid intelligence, but was unrelated to crystallised intelligence. The findings have theoretical implications for understanding the mechanisms underlying a failure to inhibit unwanted intrusions and clinical implications for disorders involving high levels of intrusive thoughts and memories.

The effect of dissociation at encoding on intrusive memories for a stressful film

The occurrence of memory intrusions after a trauma has been linked to peri-traumatic dissociation. In this study, we attempted to induce dissociation experimentally and investigate the impact on intrusive memories. A total of 39 undergraduates were randomly assigned to watch a stressful film under standard conditions or under a dual-task condition in which they simultaneously performed a tapping task. They rated their distress post-film and again after 2 weeks, and kept a diary of intrusive memories. Contrary to prediction, there were no differences in levels of distress or explicit memory between the two conditions, and the dual-task condition was followed by significantly fewer memory intrusions. Dual-task conditions may not provide a good analogue to naturally occurring dissociation. The possible preventive effects of the tapping task are discussed in terms of the dual-representation theory of post-traumatic stress disorder.

Characteristics of handicap for patients with recent onset rheumatoid arthritis: the validity of the Disease Repercussion Profile

OBJECTIVES

To investigate the applicability of the Disease Repercussion Profile (DRP) in the assessment of people with recently diagnosed rheumatoid arthritis. Previous research using this instrument has been confined to chronic samples.

METHODS

Fifty-three patients with recent onset rheumatoid arthritis completed the DRP and other commonly used clinical outcome measures.

RESULTS

The life areas of the DRP were highly interrelated, with the exception of finance. The total DRP score was associated with joint function, disability, subjective pain and coping, but was most highly associated with emotional disturbance, particularly depressive symptoms. No associations were found between measures of disease or demographic variables and DRP subscales. Activity was the area most often affected, with social life, emotions and appearance all more strongly endorsed than finances and relationships. However, whenever any of the areas was endorsed as affected, its impact was inevitably rated as very important. The pattern of self-perceived handicap was different from that reported in people with chronic arthritis.

CONCLUSIONS

These results offer evidence that the DRP provides a valid measure of handicap for patients with early illness even with relatively low levels of disability. However, handicap in early rheumatoid arthritis may be more highly associated with psychological distress than in later stages of the illness.

A cognitive neuroscience account of posttraumatic stress disorder and its treatment

Recent research in the areas of animal conditioning, the neural systems underlying emotion and memory, and the effect of fear on these systems is reviewed. This evidence points to an important distinction between hippocampally-dependent and non-hippocampally-dependent forms of memory that are differentially affected by extreme stress. The cognitive science perspective is related to a recent model of posttraumatic stress disorder, dual representation theory, that also posits separate memory systems underlying vivid reexperiencing versus ordinary autobiographical memories of trauma. This view is compared with other accounts in the literature of traumatic memory processes in PTSD, and the contrasting implications for therapy are discussed.

A blind, randomized, controlled trial of cognitive-behavioural intervention for patients with recent onset rheumatoid arthritis: preventing psychological and physical morbidity

This study examined the efficacy of a cognitive and behavioural intervention (CBT) for patients with recent onset, seropositive rheumatoid arthritis. Fifty-three participants with a diagnosis of classical or definite rheumatoid arthritis, who were seropositive and had less than 2 years of disease history were recruited into the trial. All participants received routine medical management during the study, although half were randomly allocated to receive an adjunctive psychological intervention. All pre- and post-treatment assessments were conducted blind to the allocation. Analyses were conducted of treatment completers and also by intention-to-treat. Significant differences were found between the groups at both post-treatment and 6-month follow-up in depressive symptoms. While the CBT group showed a reduction in depressive symptoms, the same symptoms increased in the Standard group. At outcome but not follow-up, the CBT group also showed reduction in C-reactive protein levels. However, the CBT group did show significant improvement in joint involvement at 6-month follow-up compared with the Standard group, indicating physical improvements above those achieved with standard care. These results indicate that cognitive-behavioural intervention offered as an adjunct to standard clinical management early in the course of RA is efficacious in producing reductions in both psychological and physical morbidity

Meta-analysis of risk factors for posttraumatic stress disorder in trauma-exposed adults

Meta-analyses were conducted on 14 separate risk factors for posttraumatic stress disorder (PTSD), and the moderating effects of various sample and study characteristics, including civilian/military status, were examined. Three categories of risk factor emerged: Factors such as gender, age at trauma, and race that predicted PTSD in some populations but not in others; factors such as education, previous trauma, and general childhood adversity that predicted PTSD more consistently but to a varying extent according to the populations studied and the methods used; and factors such as psychiatric history, reported childhood abuse, and family psychiatric history that had more uniform predictive effects. Individually, the effect size of all the risk factors was modest, but factors operating during or after the trauma, such as trauma severity, lack of social support, and additional life stress, had somewhat stronger effects than pretrauma factors.

The London Depression Intervention Trial. Randomised controlled trial of antidepressants v. couple therapy in the treatment and maintenance of people with depression living with a partner: clinical outcome and costs

BACKGROUND

Relapse of depression is associated with a criticising attitude of the patient's partner.

AIMS

To compare the relative efficacy and cost of couple therapy and antidepressant drugs for the treatment and maintenance of people with depression living with a critical partner.

METHOD

A randomised controlled trial of antidepressant drugs v. couple therapy. The subjects were 77 people meeting criteria for depression living with a critical partner.

RESULTS

Drop-outs were 56.8% [corrected] from drug treatment and 15% from couple therapy. Subjects' depression improved in both groups, but couple therapy showed a significant advantage, according to the Beck Depression Inventory, both at the end of treatment and after a second year off treatment. Adding the costs of the interventions to the costs of services used showed there was no appreciable difference between the two treatments.

CONCLUSIONS

For this group couple therapy is much more acceptable than antidepressant drugs and is at least as efficacious, if not more so, both in the treatment and maintenance phases. It is no more expensive overall.

Fear, helplessness, and horror in posttraumatic stress disorder: investigating DSM-IV criterion A2 in victims of violent crime

A DSM-IV diagnosis of posttraumatic stress disorder (PTSD) required for the first time that individuals must report experiencing intense fear, helplessness, or horror at the time of the trauma. In a longitudinal study of 138 victims of violent crime, we investigated whether reports of intense trauma-related emotions characterized individuals who, after 6 months, met criteria for PTSD according to the DSM-III-R. We found that intense levels of all 3 emotions strongly predicted later PTSD. However, a small number of those who later met DSM-III-R or ICD criteria for PTSD did not report intense emotions at the time of the trauma. They did, however, report high levels of either anger with others or shame.

Predicting PTSD symptoms in victims of violent crime: the role of shame, anger, and childhood abuse

To examine the role of cognitive-affective appraisals and childhood abuse as predictors of crime-related posttraumatic stress disorder (PTSD) symptoms, 157 victims of violent crime were interviewed within 1 month post-crime and 6 months later. Measures within 1 month post-crime included previous physical and sexual abuse in childhood and responses to the current crime, including shame and anger with self and others. When all variables were considered together, shame and anger with others were the only independent predictors of PTSD symptoms at 1 month, and shame was the only independent predictor of PTSD symptoms at 6 months when 1-month symptoms were controlled. The results suggest that both shame and anger play an important role in the phenomenology of crime-related PTSD and that shame makes a contribution to the subsequent course of symptoms. The findings are also consistent with previous evidence for the role of shame as a mediator between childhood abuse and adult psychopathology.

The timing, triggers and qualities of recovered memories in therapy

OBJECTIVES

To report descriptive data on memory recovery of traumatic material including: degree of prior amnesia, triggers to recovery, qualities of the memory and length of time taken to recover different types of memory.

DESIGN

British Psychological Society practitioners who reported having clients with recovered memories in a previous large-scale survey were contacted for an indepth interview. They each provided information on up to three such clients.

METHODS

From telephone interviews with 108 therapists, we elicited 236 detailed accounts of clients recovering a traumatic memory. Interviews were semistructured with investigator-based ratings.

RESULTS

The degree of amnesia varied widely according to therapists: some clients had prior total amnesia, others a prior vague sense or suspicion, and others prior partial memories. Time in therapy before first recall was longer for memories involving child sexual abuse than for memories of other traumas. The majority of the memories, but not all, were similar to those reported by patients with post-traumatic stress disorder: they were fragmented, accompanied by high levels of emotion, and experienced as a reliving of the original event.

CONCLUSIONS

On the basis of current understanding of memory processes, several mechanisms may be needed to explain all the data, including disruptions to the encoding and retrieval of traumatic events and errors in the attribution of the source of specific memories. It will be important to confirm these findings by interviewing clients themselves.

Emotional disclosure in school children

Recent research with adults by Pennebaker and his colleagues has found that emotional disclosure through writing about stressful events appears to have significant benefits in terms of psychological and physical health outcomes. This report describes a controlled trial of emotional disclosure, adapted for school children, with the major hypothesis that the repeated description of negative events will have beneficial effects on measures of mental health, attendance, and school performance. The sample consisted of children aged 8-13 years from four schools, a primary and a secondary school both from a suburban and an inner-city area. Children were randomly assigned to one of three conditions: writing about negative events, writing about nonemotional events, and a non-writing control group. Children in all groups were seen four times during a single week and were then followed up after 2 months with measures of health and school performance. The intervention was well received by both schools and children, and the scripts written by the emotional and nonemotional writing groups differed in content in the predicted ways. Contrary to expectation, there was little evidence of a specific effect of emotional disclosure, and several possible reasons for this are discussed. Nevertheless, there was a general reduction in symptom measures, indicating that children may have benefited from their involvement in the study. Although there are several possible explanations for our findings, they indicate that it is both feasible and potentially valuable to give children opportunities to engage in discussion about sources of stress and their reactions to them.

Predicting PTSD symptoms in victims of violent crime: the role of shame, anger, and childhood abuse

To examine the role of cognitive-affective appraisals and childhood abuse as predictors of crime-related posttraumatic stress disorder (PTSD) symptoms, 157 victims of violent crime were interviewed within 1 month post-crime and 6 months later. Measures within 1 month post-crime included previous physical and sexual abuse in childhood and responses to the current crime, including shame and anger with self and others. When all variables were considered together, shame and anger with others were the only independent predictors of PTSD symptoms at 1 month, and shame was the only independent predictor of PTSD symptoms at 6 months when 1-month symptoms were controlled. The results suggest that both shame and anger play an important role in the phenomenology of crime-related PTSD and that shame makes a contribution to the subsequent course of symptoms. The findings are also consistent with previous evidence for the role of shame as a mediator between childhood abuse and adult psychopathology.

Autobiographical memory processes and the course of depression

The authors report a 6-month follow-up study of clinically depressed patients. At baseline, 2 indexes of autobiographical memory functioning were assessed: the presence of spontaneous intrusive memories of stressful life events and performance on the Autobiographical Memory Test (J. M. G. Williams & K. Broadbent, 1986), which measures overgeneral memory. The index of overgeneral memory was associated with greater levels of spontaneous intrusion of stressful memories. Overgeneral memory did not predict outcome, but depression at follow-up was predicted by the amount of intrusion and avoidance of stressful memories, even after controlling for initial severity of psychiatric symptoms.

An investigation of shame and guilt in a depressed sample

A self-report measure of proneness to shame and guilt was administered to 86 patients with moderate to severe depression, with the prediction that there would be a positive correlation of shame with severity of depression. Contrary to other, non-clinical studies, we found that guilt but not shame was associated with levels of depression. Shame-proneness demonstrated a unique association with a stable attributional style for negative outcomes, global negative self-evaluation, submissive behaviour and internalized anger. Contrary to prediction, no relationship was found between shame- or guilt-proneness and a reported history of childhood sexual abuse.

Characteristics, context and consequences of memory recovery among adults in therapy

BACKGROUND

There are concerns that memories recovered during therapy are likely to be the result of inappropriate therapeutic techniques.

AIMS

To investigate systematically these concerns.

METHOD

One-hundred and eight therapists provided information on all clients with recovered memories seen in the past three years, and were interviewed in detail on up to three such clients.

RESULTS

Of a total of 690 clients, therapists reported that 65% recalled child sexual abuse and 35% recalled other traumas, 32% started recovering memories before entering therapy. According to therapists' accounts, among the 236 detailed client cases very few appeared improbable and corroboration was reported in 41%. Techniques to aid recall were used in 42%, but only in 22% were they used before memory recovery started.

CONCLUSIONS

Some of the data are consistent with memories being of iatrogenic origin, but other data clearly point to the need for additional explanations.

A randomized controlled trial of individual psychological debriefing for victims of violent crime

BACKGROUND

It has been suggested that giving people the opportunity talk about a traumatic experience may prevent the development of later disorder. We tested the efficacy of two brief interventions, education and psychological debriefing, designed to prevent adverse psychological reactions to criminal victimization.

METHODS

Individuals who had been the victims of a violent crime within the past month were written to and invited to take part in a study of their attitudes to crime and punishment: 2161 were contacted and 243 replied, of whom 157 were eligible and were randomly assigned either to an education condition, to a psychological debriefing plus education condition, or to an assessment only condition. Education involved providing information about normal post-traumatic reactions. Debriefing involved in-depth probing about events, thoughts and feelings experienced during the crime. Subjects were recruited from police and hospital sources and interviewed in their own homes: 138 were followed up at 6 months, and 92 at 11 months.

RESULTS

Outcome was assessed using a DSM-III-R diagnosis of PTSD, the Post-traumatic Symptom Scale, the Impact of Event Scale and the Beck Depression Inventory. All groups improved over time but there were no between-group differences.

CONCLUSIONS

No evidence was found to support the efficacy of brief one-session interventions for preventing post-traumatic symptoms in individual victims of violent crime.

Integrating psychological therapies: processes of meaning transformation

We review the role played by meaning in different schools of psychotherapy, and propose that the systematic study of meaning transformation has the potential to unify understanding of the scientific basis of psychotherapy. We describe some of the most important innate and social origins of meaning, and identify seven major themes that characterize the thinking of people with psychological disorders. We also describe how these themes are processed cognitively on multiple levels, and propose common change processes that are consistent with research in cognitive psychology. These core sets of themes and processes are offered as a first step toward a systematic study of meaning and psychotherapeutic change.

Effects of mode of writing on emotional narratives

The authors hypothesized that writing longhand about a stressful experience, compared to typing, arouses greater negative emotion. Eighty college students were randomly assigned to describe either a neutral or stressful topic by typing or writing longhand, in a 2 x 2 factorial design. Students describing the stressful topic, compared to the neutral topic, wrote for a longer period, used more words, and reported greater negative and less positive affect. Consistent with prediction, writing about a stressful experience longhand induced greater negative affect than typing, and led to more self-rated disclosure. These findings suggest a method whereby therapists can help patients control their levels of negative affect when producing a trauma narrative.

Repressive coping and self-reports of parenting

OBJECTIVES

To investigate whether women who possess a repressive coping style (repressors) self-report more positive judgments of their childhood on questionnaire and repertory grid measures compared with non-repressors.

DESIGN

Repressors (low anxiety-high defensiveness) were compared with a composite group of non-repressors, containing some low anxious (low anxiety-low defensiveness), some high anxious (high anxiety-low defensiveness), some defensive high anxious (high anxiety-high defensiveness) and some non-extreme scorers.

METHODS

Participants completed the Parental Bonding Instrument (PBI; Parker, Tupling & Brown, 1979) and a 10 x 10 repertory grid, Self-Identification Form.

RESULTS

On the PBI, repressors scored significantly higher than non-repressors on paternal care and significantly lower on paternal overprotection. There were no group differences for maternal measures. On the repertory grid, repressors compared with non-repressors perceived (a) themselves as significantly closer to their father, a woman they like, and their ideal partner, and significantly further from a woman they dislike, and a man they dislike; and (b) their father as significantly closer to a woman they like, a partner/person they admire, and an ideal partner. In addition, repressors were significantly tighter on construing than non-repressors.

CONCLUSIONS

The results supported the hypothesis that repressors would rate their interactions with their fathers more positively than non-repressors when allowed to do so on self-report measures.

Intrusive memories in depression and posttraumatic stress disorder

This study compared the stressors and consequent intrusive memories reported by matched samples of patients with posttraumatic stress disorder (PTSD) and major depression. Although intrusive memories were slightly more common among PTSD patients, both quantitative and qualitative measures revealed few differences between the groups. PTSD patients were more likely to have experienced personal illness or assault, and depressed patients family deaths and illness, and interpersonal events. Factor analysis of the associated emotions and memory characteristics suggested the existence of specific links between fear and reliving, and helplessness and out-of-body experiences. Possible inhibitory relationships between fear and sadness, and between guilt and anger, were also noted.

Acute stress disorder and posttraumatic stress disorder in victims of violent crime

OBJECTIVE

In a group of crime victims recruited from the community, the authors investigated the ability of both a diagnosis of acute stress disorder and its component symptoms to predict posttraumatic stress disorder (PTSD) at 6 months.

METHOD

A mixed-sex group of 157 victims of violent assaults were interviewed within 1 month of the crime. At 6-month follow-up 88% were reinterviewed by telephone and completed further assessments generating estimates of the prevalence of PTSD.

RESULTS

The rate of acute stress disorder was 19%, and the rate of subsequent PTSD was 20%. Symptom clusters based on the DSM-IV criteria for acute stress disorder were moderately strongly interrelated. All symptom clusters predicted subsequent PTSD, but not as well as an overall diagnosis of acute stress disorder, which correctly classified 83% of the group. Similar predictive power could be achieved by classifying the group according to the presence or absence of at least three reexperiencing or arousal symptoms. Logistic regression indicated that both a diagnosis of acute stress disorder and high levels of reexperiencing or arousal symptoms made independent contributions to predicting PTSD.

CONCLUSIONS

This exploratory study provides evidence for the internal coherence of the new acute stress disorder diagnosis and for the symptom thresholds proposed in DSM-IV. As predicted, acute stress disorder was a strong predictor of later PTSD, but similar predictive power may be possible by using simpler criteria.

Recovered memories of trauma: phenomenology and cognitive mechanisms

We outline four current explanations for the reported forgetting of traumatic events, namely repression, dissociation, ordinary forgetting, and false memory. We then review the clinical and survey evidence on recovered memories, and consider experimental evidence that a variety of inhibitory processes are involved in everyday cognitive activity including forgetting. The data currently available do not allow any of the four explanations to be rejected, and strongly support the likelihood that some recovered memories correspond to actual experiences. We propose replacing the terms repression and dissociation as explanations of forgetting with an account based on cognitive science.

Intrusive memories and depression in cancer patients

Matched samples of depressed and nondepressed cancer patients were interviewed about past life events, particularly experiences of death and illness. They identified and described any spontaneous intrusive visual memories they had experienced in the past week corresponding to these events. About one quarter reported such memories and, as predicted, the majority of intrusive memories concerned illness, injury and death. The mean levels of intrusion and avoidance were equivalent to patients with post-traumatic stress disorder. Consistent with prediction, depressed patients reported significantly more intrusive memories than controls, and described the memories as typically beginning with or being exacerbated by the onset of depression. Greater numbers of intrusive memories were associated with more maladaptive coping, and greater avoidance with deficits in autobiographical memory functioning.

Dependency and self-criticism as predictors of depression in young doctors

Brief measures of depression and of dependency and self-criticism, personality factors believed to convey vulnerability to depression, were administered to 318 medical students. Depression was subsequently measured 2 years later (in the highly stressful 1st postgraduate year) and 10 years later when careers were established. When initial symptom levels and concurrent workload were controlled, dependency and, more particularly, self-criticism were significant predictors of depression for male doctors in the 1st postgraduate year. For female doctors, self-criticism was the only significant predictor. Ten years later, the predictive effects for male doctors were similar, but rather weaker, whereas none of the variables predicted depression in female doctors. Implications for preventive interventions are discussed.

Repressive coping and the directed forgetting of emotional material

Using a directed forgetting task, the authors tested in 2 experiments the hypothesis that repressors would be superior to controls in forgetting negative experimental material. Consistent with previous studies, there was an overall directed forgetting effect, with significantly more to-be-remembered material recalled than to-be-forgotten (TBF) material. In both experiments, repressors forgot more negatively valenced words in the TBF set than did nonrepressors, suggesting that repressors have an enhanced capability for using retrieval inhibition. The data offer preliminary support for a cognitive account of repressors' deficits in recalling negative autobiographical memories.

Intrusive cognitions, coping strategies and emotional responses in depression, post-traumatic stress disorder and a non-clinical population

Patients with major depression but not PTSD, patients with PTSD with or without comorbid depression, and a sample of non-clinical controls, were interviewed about their most prominent intrusive cognition, coping strategies and emotional responses. Evaluative thoughts were more likely to be reported by the depressed sample and the control sample. They were also common in the PTSD group, but other types of intrusions were also common, particularly personal memory. All three groups reported a wide variety of different types of intrusive cognition, both singly and in combination. These included elaborative cognitions, future-oriented thoughts or images that represented an elaboration of a specific personal memory. Cognitions were more frequent, unacceptable, and intrusive in the PTSD group in the month preceding interview, but the two clinical groups did not differ in the use of or effectiveness of coping strategies, or in emotional responses.

Memory processes and the course of anxiety and depression in cancer patients

BACKGROUND

Intrusive memories of stressful events, many involving illness and death, are found in a minority of depressed cancer patients, and may predict the course of anxiety and depression.

METHOD

Matched samples of mild to moderately depressed and non-depressed cancer patients were followed up after 6 months. Anxiety and depression at follow-up were related to measures of intrusive memories of stressful life events and autobiographical memory functioning that had been assessed at baseline.

RESULTS

Levels of anxiety and depression remained fairly constant over time in the two groups, and the depressed group continued to experience high levels of intrusive memories. The presence of intrusive memories at baseline, and the extent to which these memories were consciously avoided, predicted greater anxiety at follow-up, even after controlling for initial severity of physical and psychiatric symptoms. None of the measures of memory functioning predicted levels of depression at follow-up.

CONCLUSIONS

Intrusive memories appear to be a marker of more prolonged psychopathology in cancer patients and may respond to direct therapeutic intervention.

The need for psychiatric treatment in the general population: the Camberwell Needs for Care Survey

BACKGROUND

This paper presents the first results of a two-stage psychiatric population survey, which uses a new method of directly evaluating needs for specific psychiatric treatment and the extent to which they have been met.

METHOD

The sample was drawn at random from the population of an area of inner south London with high levels of deprivation. Seven hundred and sixty subjects aged 18-65 completed the GHQ-28. All those scoring > 5 and half of the rest were invited to take part in the second stage, comprising measures of mental state (SCAN), social role performance (SRPS), life events and difficulties (LEDS) and a Treatment Inventory. This information was used to rate the community version of the Needs for Care Assessment (NFCAS-C).

RESULTS

In all, 408 subjects were interviewed in the second stage. The weighted 1 month prevalence of hierarchically ordered ICD-10 psychiatric disorders was 9.8%, the 1 year prevalence 12.3%. The equivalent prevalences for depressive episode were 3.1% and 5.3% respectively, while those for anxiety states were both 2.8%. At interview nearly 10% of the population were identified as having a need for the treatment of a psychiatric condition. This rose to 10.4% if the whole of the preceding year was assessed. Less than half of all potentially meetable needs were met. There was only partial overlap between diagnosis and an adjudged need for treatment.

CONCLUSION

A majority of people with mental health problems do not have proper treatment; given more resources and greater public and medical awareness, most could be treated by family doctors.

Dependency and self-criticism as predictors of depression in young doctors

Brief measures of depression and of dependency and self-criticism, personality factors believed to convey vulnerability to depression, were administered to 318 medical students. Depression was subsequently measured 2 years later (in the highly stressful 1st postgraduate year) and 10 years later when careers were established. When initial symptom levels and concurrent workload were controlled, dependency and, more particularly, self-criticism were significant predictors of depression for male doctors in the 1st postgraduate year. For female doctors, self-criticism was the only significant predictor. Ten years later, the predictive effects for male doctors were similar, but rather weaker, whereas none of the variables predicted depression in female doctors. Implications for preventive interventions are discussed.

The assessment of parenting using the parental bonding instrument: two or three factors?

BACKGROUND

The Parental Bonding Instrument (PBI) is a widely used measure of parenting, and is usually used to measure two parenting dimensions, care and over-protection. However, there is disagreement in the research literature about whether the PBI is best used as a two-factor or a three-factor measure.

METHOD

PBI scores from 583 US and 236 UK students were factor analysed to assess whether a three-factor solution was more satisfactory than a two-factor solution.

RESULTS

A three-factor (care, denial of psychological autonomy and encouragement of behavioural freedom) solution was found to be more satisfactory than a two-factor solution. Using the three-factor solution, group differences that were not apparent with the two-factor solution were identified and it was found that the parenting behaviours associated with depression could be more accurately identified.

CONCLUSION

The authors suggest that with modifications, the PBI could be used to measure three parenting variables (care, denial of psychological autonomy and encouragement of behavioural freedom), which would allow greater accuracy of prediction and a greater understanding of underlying processes.
