Cognitive behavioral interventions for adolescents with cystic fibrosis

Do single-case experimental designs lead to randomised controlled trials of cognitive behavioural therapy interventions for adolescent anxiety and related disorders recommended in the National Institute of Clinical Excellence guidelines? A systematic review

Background

Although Cognitive Behavioural Therapy (CBT) is effective for 60% of adolescents with anxiety disorders, only 36% are in remission post-intervention. This indicates that more effective treatments are needed which should be reflected in the NICE guidelines. We hypothesised that Single-case experimental designs (SCEDs) may provide a framework for accelerating the development of novel interventions. The primary purpose of this review was to investigate whether SCEDs are currently followed by randomised controlled trials (RCTs) of CBT intervention for adolescent anxiety disorders named in the NICE guidelines. The secondary objective was to investigate whether using SCEDs prior to RCTs could be a helpful approach.

Method

For the primary search of SCEDs five databases were used (PsycINFO, PubMed, PsycArticles, Web of Science and ProQuest). Nineteen articles met eligibility criteria including a total of 107 participants. For the secondary search of RCTs named in the NICE guidelines for adolescent anxiety disorders 53 articles met inclusion criteria and were included in the systematic review.

Results

The 19 SCED studies included in the review were conducted with participants with a diverse range of anxiety disorders and across a range of CBT formats. Two of the SCEDs were followed by RCTs, but neither of these were named in the NICE guidelines for anxiety disorders. All of the SCEDs identified were rated as low quality with none meeting the criteria for the highest or second highest quality rating. From the secondary searches, none of the RCTs named in the NICE guide were preceded by SCEDs.

Conclusions

It was concluded that currently SCEDs were not followed by RCTs of CBT interventions named in the NICE guidelines for adolescent anxiety disorders. However, it was suggested that SCEDs may provide an important framework for the development of more effective interventions for adolescents with anxiety.

Effectively Supporting Youth with Chronic Illness in Schools: External Partnerships and Training Recommendations

Across Western countries, approximately 15% to 20% of school-aged children and adolescents have a health-related disorder, with incidence rates of childhood chronic health conditions (CHCs) increasing. This contribution comprehensively reviews disease-level, school-level, and systems-level issues related to effectively supporting children with CHCs succeed from both psychosocial and educational perspectives. This article also delineates training needs as they pertain to graduate preparation and/or professional development to equip school personnel to appropriately address students' needs. The article concludes with recommendations for evidence-based prevention and intervention strategies and potential avenues for interdisciplinary collaboration and models of coordinated care for these medically compromised youth.

Pilot RCT of a telehealth intervention to reduce symptoms of depression and anxiety in adults with cystic fibrosis

BACKGROUND

Adults with cystic fibrosis (awCF) have higher levels of depression and anxiety than community samples. The Coping and Learning to Manage Stress with CF (CALM) intervention was developed for awCF reporting elevated symptoms of depression or anxiety.

METHODS

In this pilot study, awCF were randomly assigned to either six telehealth sessions (CALM; n = 15) or treatment-as-usual (TAU; n = 16). Primary outcomes were depression and anxiety. Secondary outcomes were coping self-efficacy and health-related quality of life (HrQOL). Tertiary outcomes were feasibility, acceptability, and satisfaction. Assessments were completed at baseline, post-intervention, and 3-month follow-up. Group differences were examined via independent samples t-tests. Effect size (ES) was calculated via Cohen's d to provide a measure of the magnitude of the treatment effect.

RESULTS

At post-intervention, the CALM group had a lower mean score than the TAU group for depression (medium ES) and anxiety (large ES). The CALM group had higher (i.e., better) mean scores than the TAU group for coping (large ES) and HrQOL domains of Social Functioning (large ES) and Vitality (large ES). Most treatment gains were not sustained at 3-month follow-up. CALM was feasible, requiring <12 min. for setup and scheduling, and allowed seamless participation when hospitalized. Mean scores for acceptability and satisfaction indicated that most participants either agreed or strongly agreed that CALM was acceptable and satisfactory.

CONCLUSIONS

CALM shows promise as an intervention to reduce symptoms of depression and anxiety and improve coping and HrQOL. Next steps are to add a booster session and examine CALM via a multi-site RCT.

What factors influence healthcare professionals to refer children and families to paediatric psychology?

OBJECTIVES

This study aimed to investigate factors influencing referral of children with physical illness to paediatric psychology. Due to high rates of mental health problems within this population, studies have shown that referral to paediatric psychology should be increased. However, few studies have examined factors shaping healthcare professionals' referral behaviour.

METHODS

This study used the theory of planned behaviour to develop a questionnaire which explores factors influencing the referral of children and families to paediatric psychology. Psychometric properties of the questionnaire were examined.

RESULTS

The questionnaire was found to have good reliability and validity. The main constructs of the theory of planned behaviour were useful in predicting intention to refer to paediatric psychology. Specific beliefs about referral were shown to influence intention to refer.

CONCLUSION

Findings suggest that individual attitudes and beliefs can impact healthcare professionals' referral behaviour, indicating that multidisciplinary interventions and inter-professional education relating to the psychological aspects of illness are required.

How can adolescent aggression be reduced? A multi-level meta-analysis

Aggressive behaviour among adolescents has significant social and economic costs. Numerous attempts have been made to intervene to reduce aggression in adolescents. However, little is known about what factors enhance or diminish intervention effectiveness. The present systematic review and meta-analysis, therefore, seeks to quantify the effectiveness of interventions to reduce aggressive behaviour in adolescents and to identify when and for whom such interventions work best. Sixteen databases were searched for randomised controlled trials that assessed interventions to reduce aggression among adolescents. After screening 9795 records, 95 studies were included. A multi-level meta-analysis found a significant overall small-to-medium effect size (d = 0.28; 95% CI [0.17, 0.39]). More effective interventions were of shorter duration, were conducted in the Middle East, were targeted at adolescents with higher levels of risk, and were facilitated by intervention professionals. Potentially active ingredients were classified using the Behaviour Change Technique Taxonomy. Behavioural practice and problem solving were components of more effective interventions targeted at the general population. Overall the findings indicate that psychosocial interventions are effective in reducing adolescent aggression. Future trials need to assess the effect of individual techniques and their combination to identify the key components that can reduce aggression in adolescents.

Psychological interventions for mental health disorders in children with chronic physical illness: a systematic review

BACKGROUND

Children with chronic physical illness are significantly more likely to develop common psychiatric symptoms than otherwise healthy children. These children therefore warrant effective integrated healthcare yet it is not established whether the known, effective, psychological treatments for symptoms of common childhood mental health disorders work in children with chronic physical illness.

METHODS

EMBASE, MEDLINE, PsycINFO and CINAHL databases were searched with predefined terms relating to evidence-based psychological interventions for psychiatric symptoms in children with chronic physical illness. We included all studies (randomised and non-randomised designs) investigating interventions aimed primarily at treating common psychiatric symptoms in children with a chronic physical illness in the review. Two reviewers independently assessed the relevance of abstracts identified, extracted data and undertook quality analysis.

RESULTS

Ten studies (209 children, including 70 in control groups) met the criteria for inclusion in the review. All studies demonstrated some positive outcomes of cognitive behavioural therapy for the treatment of psychiatric symptoms in children with chronic physical illness. Only two randomised controlled trials, both investigating interventions for symptoms of depression, were found.

CONCLUSIONS

There is preliminary evidence that cognitive behavioural therapy has positive effects in the treatment of symptoms of depression and anxiety in children with chronic physical illness. However, the current evidence base is weak and fully powered randomised controlled trials are needed to establish the efficacy of psychological treatments in this vulnerable population.

Psychological interventions for individuals with cystic fibrosis and their families

BACKGROUND

With increasing survival estimates for individuals with cystic fibrosis, long-term management has become an important focus. Psychological interventions are largely concerned with adherence to treatment, emotional and social adaptation and health-related quality of life. We are unaware of any relevant systematic reviews.

OBJECTIVES

To determine whether psychological interventions for people with cystic fibrosis provide significant psychosocial and physical benefits in addition to standard medical care.

SEARCH METHODS

Studies were identified from two Cochrane trials registers (Cystic Fibrosis and Genetic Disorders Group; Depression, Anxiety and Neurosis Group), Ovid MEDLINE and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search of the Cystic Fibrosis and Genetic Disorders Group's register: 19 December 2013.Most recent search of the Depression, Anxiety and Neurosis Group's register: 12 November 2013.

SELECTION CRITERIA

Randomised controlled studies of a broad range of psychological interventions evaluating subjective and objective health outcomes, such as quality of life or pulmonary function, in individuals of all ages with cystic fibrosis and their immediate family. We were interested in psychological interventions, including psychological methods within the scope of psychotherapeutic or psychosomatic mechanism of action (e.g. cognitive behavioural, cognitive, family systems or systemic, psycho-dynamic, or other, e.g. supportive, relaxation, or biofeedback), which were aimed at improving psychological and psychosocial outcomes (e.g. quality of life, levels of stress or distress, psychopathology, etc.), adaptation to disease management and physiological outcomes.

DATA COLLECTION AND ANALYSIS

Three authors were involved in selecting the eligible studies and two of these authors assessed their risk of bias.

MAIN RESULTS

The review includes 16 studies (eight new studies included in this update) representing data from 556 participants. Studies are diverse in their design and their methods. They cover interventions with generic approaches, as well as interventions developed specifically to target disease-specific symptoms and problems in people with cystic fibrosis. These include cognitive behavioural interventions to improve adherence to nutrition or psychosocial adjustment, cognitive interventions to improve adherence or those associated with decision making in lung transplantation, a community-based support intervention and other interventions, such as self-hypnosis, respiratory muscle biofeedback, music therapy, dance and movement therapy, and a tele-medicine intervention to support patients awaiting transplantation.A substantial proportion of outcomes relate to adherence, changes in physical status or other specific treatment concerns during the chronic phase of the disease.There is some evidence that behavioural interventions targeting nutrition and growth in children (4 to 12 years) with cystic fibrosis are effective in the short term. Evidence was found that providing a structured decision-making tool for patients considering lung transplantation improves patients' knowledge of and expectations about the transplant, and reduces decisional conflict in the short term. One study about training in biofeedback-assisted breathing demonstrated some evidence that it improved some lung function measurements. Currently there is insufficient evidence for interventions aimed at other aspects of the disease process.

AUTHORS' CONCLUSIONS

Currently, insufficient evidence exists on psychological interventions or approaches to support people with cystic fibrosis and their caregivers, although some of the studies were promising. Due to the heterogeneity between studies, more of each type of intervention are needed to support preliminary evidence. Multicentre studies, with consequent funding implications, are needed to increase the sample size of these studies and enhance the statistical power and precision to detect important findings. In addition, multicentre studies could improve the generalisation of results by minimizing centre or therapist effects. Psychological interventions should be targeted to illness-specific symptoms or behaviours to demonstrate efficacy.

Developmental and psychosocial issues in cystic fibrosis

Cystic fibrosis (CF) is a multisystemic life-limiting genetic disorder, primarily affecting respiratory functioning. Most patients with CF are diagnosed by 2 years of age, and the current median predicted survival rate is 37.4 years old, with 95% of patients dying from complications related to pulmonary infection. Given the chronic, progressive, and disabling nature of CF, multiple treatments are prescribed, most on a daily basis. Thus, this illness requires children, with the aid of their families, to adopt multiple health-related behaviors in addition to managing more typical developmental demands. The morbidity and mortality factors pose cognitive, emotional, and behavioral challenges for many children with CF and their families. This article applies a developmental perspective to describing the psychosocial factors affecting psychological adjustment and health-related behaviors relevant to infants, preschool and school-age children, and adolescents with CF. Topics particularly pertinent to developmental periods and medical milestones are noted, with clinical implications highlighted.

Associations of psychosocial factors with health outcomes among youth with cystic fibrosis

PURPOSE

The purpose of this study was to examine the relationship of strains, resources, feelings, and behaviors about treatment adherence reported by youth with cystic fibrosis (CF) with repeated clinic measures of their pulmonary function and nutritional status.

METHODS

Linear mixed models, stratified by gender, adjusting for age, were used to examine the effects of strains, resources, and adherence behaviors on repeated pulmonary function and nutritional status measures. All 10-21 years old with CF at the Minnesota Cystic Fibrosis Center were invited by mail to participate. Of these 177 youth, 51% (43 boys, 47 girls) returned surveys. Forced expiratory volume in 1 sec and predicted weight-for-height were extracted from participants' clinic records for the 18 months following receipt of the survey.

RESULTS

Females showed significantly greater variability in repeated measures of pulmonary function and nutritional status compared to males. Parent-youth strains, physical strains, activity limitations, and cough suppression had significant effects on the 18-month mean of pulmonary function measures for females, but only physical strains had a significant effect for males.

CONCLUSION

Compared to males, females experienced more strains and poorer treatment adherence, which may be factors associated with declines in pulmonary function observed among females with CF during the adolescent years.

Psychological interventions for people with cystic fibrosis and their families

BACKGROUND

With increasing survival estimates for cystic fibrosis (CF) long-term management has become an important focus. Psychological interventions are largely concerned with adherence to treatment, emotional and social adjustments and quality of life. We are unaware of any relevant systematic reviews.

OBJECTIVES

Assess whether psychological interventions for CF provide significant psychosocial and physical benefits in addition to standard care.

SEARCH STRATEGY

Trials were identified from two Cochrane trial registers (CF and Genetic Disorders Group; Depression, Anxiety and Neurosis Group), Ovid MEDLINE and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search: September 2007.

SELECTION CRITERIA

Randomised controlled trials of a broad range of psychological interventions in children and adults with CF and their immediate family.

DATA COLLECTION AND ANALYSIS

Two authors independently selected relevant trials and assessed their methodological quality.

MAIN RESULTS

The review includes 13 studies (five new at this update) representing data from 529 participants. Studies mainly assessed behavioural and educational interventions:1. gene pre-test education counselling for relatives of those with CF;2. biofeedback, massage and music therapy to assist physiotherapy;3. behavioural and educational interventions to improve dietary intake and airway clearance;4. self-administration of medication and education to promote independence, knowledge and quality of life; and5. systemic interventions promoting psychosocial functioning.A substantial proportion of outcomes were educational or behavioural relating to issues of adherence, change in physical status or other specific treatment concerns during the chronic phase of the disease. Some evidence was found for relative's acceptance of a genetic test for carrier status when using home-based rather than clinic-based information leaflets and testing. There is some evidence that behavioural interventions improve emotional outcomes in people with CF and their carers, and that psychoeducational interventions improve knowledge in the short term. There was no consistent effect on lung function, although one small study showed that biofeedback-assisted breathing re-training helped improve some lung function measurements. Some studies point to educational and behavioural interventions aiding nutrition and growth in people with CF. Currently there is insufficient evidence for interventions aimed at other aspects of the disease process.

AUTHORS' CONCLUSIONS

Currently no clear evidence exists on the best psychological interventions to help people with CF and their carers manage the disease. Trials of interventions to improve adherence to treatment are needed. Multicentre approaches, with consequent funding implications, will increase the sample size of trials and enhance the power and precision of their findings.

Case study: longitudinal treatment of adolescents with depression and inflammatory bowel disease

OBJECTIVE

To assess longitudinal maintenance of improvements in depression, anxiety, global functioning, and physical health perception in 11 adolescents at 6 and 12 months following completion of manual-based cognitive-behavioral therapy.

METHOD

Standardized instruments assessed follow-up changes in depression, anxiety, physical health, and global psychological functioning.

RESULTS

At both assessments, 10 adolescents did not meet criteria for mood disorders. Improvements in depression, anxiety, global functioning, and physical health perceptions at completion of the cognitive-behavioral therapy were maintained during the 12-month period. Additional cognitive-behavioral therapy sessions (mean = 4.36; SD = 4.37) and psychopharmacology (n = 5) were required during the follow-up period.

CONCLUSIONS

CBT with maintenance sessions and medication offers promise to adolescents facing comorbid depressive and physical disorders.

Cognitive-behavioral therapy for depression in adolescents with inflammatory bowel disease: a pilot study

OBJECTIVE

To evaluate the safety and feasibility of cognitive-behavioral therapy (CBT) for depression in physically ill adolescents.

METHOD

In an open trial, 11 adolescents (12-17 years) with inflammatory bowel disease and either major or minor depression underwent 12 sessions of a manual-based CBT enhanced by social skills, physical illness narrative, and family psychoeducation components. Standardized instruments assessed pre- to posttreatment changes in depression, physical health, global psychological functioning, and social functioning. Perceived helpfulness and satisfaction with CBT were assessed.

RESULTS

There were significant reductions in DSM-IV depression diagnoses and depressive symptoms and improvements in global psychological and social functioning. Adolescents' perceptions of their general health and physical functioning improved, although illness severity measures were unchanged. High subject satisfaction and helpfulness ratings for CBT were found along with no adverse events and high subject adherence.

CONCLUSIONS

A manual-based CBT approach adapted to treat depression in physically ill adolescents appears to be a safe, feasible, and promising intervention.

Individualized daily schedules for hospitalized adolescents with cystic fibrosis

INTRODUCTION

This article describes the effects of an individualized patient schedule on satisfaction and clinical outcomes for patients with cystic fibrosis admitted to an adolescent unit.

METHOD

Data on airway clearance treatments, physical therapy attendance, and school attendance were collected for patients who used the individualized schedule and for historic controls. Patients who were admitted following implementation of the schedule were asked to complete a brief survey about their inpatient care shortly before or after hospital discharge.

RESULTS

Patients who used the schedule were more likely to report that their care was often or always delivered exactly as they expected and to believe that they were involved in care decisions as much as they wanted to be. Eighty-seven percent believed that using the individualized schedule made their stay a little or much better compared to past hospitalizations. There was no change in physical therapy, airway clearance, and school attendance.

DISCUSSION

Engaging hospitalized adolescents with cystic fibrosis in the design of their individualized daily schedule is a win-win proposition, resulting in improved satisfaction while maintaining clinical outcomes.

Psychological interventions for cystic fibrosis

BACKGROUND

As survival estimates for cystic fibrosis (CF) steadily increase long-term management has become an important focus for intervention. Psychological interventions are largely concerned with emotional and social adjustments, adherence to treatment and quality of life, however no systematic review of such interventions has been undertaken for this disease.

OBJECTIVES

To describe the extent and quality of effectiveness studies utilising psychological interventions for CF and whether these interventions provide significant psychosocial and physical benefits in addition to standard care.

SEARCH STRATEGY

Relevant trials were identified from searches of Ovid MEDLINE, the Cochrane trial registers for CF and Depression, Anxiety and Neurosis Groups and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search: April 2003.

SELECTION CRITERIA

This review included RCTs and quasi-randomised trials. Study participants were children and adults diagnosed with CF, and their immediate family members. Psychological interventions were from a broad range of modalities and outcomes were primarily psychosocial, although physical outcomes and cost effectiveness were also considered.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected relevant trials and assessed their methodological quality. For binary and continuous outcomes a pooled estimate of treatment effect was calculated for each outcome.

MAIN RESULTS

This review is based on the findings of eight studies, representing data from a total of 358 participants. Studies fell into four conceptually similar groups: (1) gene pre-test education counselling for relatives of those with CF (one study); (2) biofeedback, massage and music therapy to assist physiotherapy (three studies); (3) behavioural intervention to improve dietary intake in children up to 12 years (three studies); and (4) self-administration of treatments to improve quality of life in adults (one study). Interventions were largely educational or behavioural, targeted at specific treatment concerns during the chronic phase. No completed studies concentrating on complex treatment approaches were found. There is some evidence that behavioural interventions can improve emotional outcomes in people with CF and their carers. There was no consistent effect on lung function although one small study showed that biofeedback assisted breathing re-training was associated with improvement in some measures of spirometric lung function. Insufficient evidence is available at this point for interventions aimed at other aspects of the disease process.

REVIEWER'S CONCLUSIONS

Multicentre approaches are required to increase the sample sizes of studies in the psychosocial field and to enhance the power and precision of the findings. This has consequent implications for funding.

Psychiatric issues in pulmonary disease

This article has attempted to provide an overview of the clinical literature regarding the psychological issues facing patients with pulmonary disease, depending on when the illness begins in the life span, because different developmental tasks are disrupted. Patients must contend with side effects of medication that may mimic or exacerbate psychiatric disorders. The main drug interactions for psychiatrists to be aware of in this patient population occur between rifampin, or theophylline and psychotropic medications. In lung transplant recipients on cyclosporine therapy, the antidepressant drug nefazadone may cause increased cyclosporine levels. Psychiatrists must be aware of the risks, benefits, and survival statistics; educate patients; and ascertain whether the patient is competent to make medical decisions regarding treatment procedures.

Hopkins Teen Central: Assessment of an internet-based support system for children with cystic fibrosis

Support groups are an important therapeutic intervention for patients with chronic debilitating illnesses. Patients who are difficult to assemble in one physical location may benefit from participating in an electronic support group (ESG). ESGs for adolescents have not been evaluated, although studies have shown a benefit to adult ESGs. Our goals were to create a web-based support service for adolescents with cystic fibrosis (CF) and to qualitatively and quantitatively measure the effects that such a support site could have on patients' relationships with the clinic faculty and staff, access to and interaction with peers with CF, and understanding of CF.

METHODS

A highly interactive ESG was developed after discussions with a team of CF specialists and patients. Eighteen of 37 teenagers with CF agreed to use this site. Each patient was asked to assess his or her perceived availability of and comfort with the clinic staff and faculty, perceived support available through peers, knowledge about CF, and perceived usefulness of the Internet as a support tool.

RESULTS

Participants logged into the site an average of 4 times each month. Teens who owned home computers accessed the site somewhat more frequently than did teens who were provided with home Internet access for the study. Most activity occurred in those sections of the site that described the participants and that allowed them to socialize. Over one half of the participants e-mailed each other at least once a week, with 77% e-mailing peers at least every other week. There was no significant difference in the participants' scores on a quiz about CF at the beginning and the end of the study; however, there was a significant decrease in perceptions about their knowledge about CF. At the conclusion of the study, participants believed that they had more friends who they could relate to than they did at the beginning of the study. Clinic staff noticed an increase in references to peers among the group who were using the site. In addition, 4 of the teens expressed a desire to get together to meet each other as a result of their interactions on the web site. There was no significant change in perceptions about the perceived availability and comfort with the clinic staff and faculty, support available through peers, knowledge about CF, and the usefulness of the Internet as a support environment. Managing the project was extremely easy, with virtually no technical or procedural issues arising during the study.

CONCLUSIONS

Teenagers with a chronic disease will actively participate in an ESG. The social and expressive aspects of their involvement with this support group hold much promise.

Self-hypnosis for patients with cystic fibrosis

This report documents the utility of self-hypnosis in patients with cystic fibrosis (CF). Sixty-three patients 7 years of age or older were offered the opportunity to be taught self-hypnosis by their pulmonologist. Forty-nine agreed to learn it. Patients generally were taught hypnosis in one or two sessions. The outcome of hypnotherapy was determined by patients' answers to open-ended questions regarding their subjective evaluation of the efficacy of hypnosis. The average age of the 49 patients who were taught and used self-hypnosis was 18.1 years (range, 7-49 years). Many of the patients used hypnosis for more than one purpose, including relaxation (61% of patients), relief of pain associated with medical procedures (31%), headache relief (16%), changing the taste of medications to make the flavor more palatable (10%), and control of other symptoms associated with CF (18%). The patients successfully utilized self-hypnosis 86% of the time. No symptoms worsened following hypnotherapy. Sixteen patients chose to practice hypnosis on their own for a half year or longer. In conclusion, with the use of self-hypnosis, patients with CF can quickly learn to enhance their control over discomforts associated with therapy and their disease. Consideration should be given to making instruction in self-hypnosis available to patients with CF.
