Pergolizzi J, LeQuang JAK, Coluzzi F, Magnusson P, Lara-Solares A, Varrassi G. Considerations for Pain Assessments in Cancer Patients: A Narrative Review of the Latin American Perspective. Cureus 2023; 15:e40804. [PMID: 37489190 PMCID: PMC10363018 DOI: 10.7759/cureus.40804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 06/21/2023] [Indexed: 07/26/2023] Open
Abstract
Cancer incidence in Latin America is lower than in Europe or the United States but morbidity and mortality rates are disproportionately high. A barrier to adequate pain control is inadequate pain assessment, which is a relatively easy and inexpensive metric. The objective of this narrative review is to describe pain assessment for cancer patients in Latin America. Cultural factors may influence pain perception, including contextualizing pain as noble or natural suffering and aspects of what is now called "spiritual pain." Unlike other painful conditions, cancer pain may be strongly associated with existential fear, psychosocial distress, anxiety, and spiritual concerns. Pain assessment allows not just quantification of pain intensity but may elucidate pain mechanisms involved or psychosocial aspects that may color the pain. Many current pain assessment instruments capture only pain intensity, which is but one aspect of the pain experience; some have expanded to include functional assessments, mental health status evaluations, and quality of life metrics. A quality-of-life assessment may be appropriate for cancer patients since chronic pain can severely impact function, which can in turn create a vicious cycle by exacerbating pain. The incidence of cancer in Latin America is expected to increase in the ensuing years. Better pain assessment and clinician education are needed to help manage pain in this large and growing patient population.

Park H, Kim KE, Moon E, Kang T. Psychometric Properties of Assessment Tools for Depression, Anxiety, Distress, and Psychological Problems in Breast Cancer Patients: A Systematic Review. Psychiatry Investig 2023; 20:395-407.

Abstract
OBJECTIVE Various and accurate psychiatric assessments in patients with breast cancer who frequently suffer from psychological problems due to long-term survivors are warranted. This systematic review aimed to investigate the current evidence on psychometric properties of psychiatric assessment for evaluating psychological problems in breast cancer patients. METHODS This systematic review progressed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Four electronic databases such as Web of Science, PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched. This study protocol was registered on Open Science Framework. RESULTS Of the 2,040 articles, 21 papers were finally included. Among them, only five studies showed the performance of psychiatric assessment tools. Among 13 assessment tools used in the selected articles, the Hospital Anxiety and Depression Scale (HADS), Distress Thermometer (DT), or Mini-Mental Adjustment to Cancer Scale was frequently used for the evaluation of psychological problems. The DT and Psychosocial Distress Questionnaire-Breast Cancer showed acceptable performances for the prediction of depression and anxiety assessed by the HADS. CONCLUSION This systematic review found psychiatric assessment tools with acceptable reliability and validity for breast cancer patients. However, comparative studies on reliability and validity of various scales are required to provide useful information for the selection of appropriate assessment tools based on the clinical settings and treatment stages of breast cancer. Joint research among the fields of psychiatry and breast surgery is needed for research to establish the convergent, concurrent, and predictive validity of psychiatric assessment tools in breast cancer patients.

Normalization of the Mini-MAC (Mental Adjustment to Cancer) Questionnaire among Cancer Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312603. [PMID: 34886329 PMCID: PMC8656664 DOI: 10.3390/ijerph182312603] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 11/26/2021] [Accepted: 11/27/2021] [Indexed: 11/16/2022]
Abstract
Cancer is associated with discomfort and many changes in patients’ lives to which they must adapt. The main objective of the study was to assess the use of the mini-MAC questionnaire scale among persons diagnosed with malignant cancer and to develop standards allowing differentiation of patients with diagnosed cancer in terms of their style of adjustment to the disease. The mini-MAC questionnaire is a widely used tool in assessing coping strategies among cancer patients. Sten standards have been developed to determine the level of results on the questionnaire scales in the low–average–high categories. The study included 1187 patients diagnosed with malignant cancer who are covered by outpatient care at the Maria Sklodowska-Curie Institute—Oncology Center in Warsaw. The questionnaire concerning mental adjustment to cancer was used (mini-MAC). Patients with cancer most often adopt strategies of fighting spirit and positive reevaluation. The variables that differentiate the results most significantly include gender, presence of metastasis, and the state of undergoing chemotherapy. The mini-MAC questionnaire should be a tool for psycho-oncological diagnosis of patients’ attitudes towards cancer. The obtained results indicate that cancer patients are characterized by their constructive style of adjustment to the disease.

Abstract
This study evaluated the functioning of children in early childhood education classroom routines, using the 3M Functioning in Preschool Routines Scale. A total of 366 children aged 36 to 70 months and 22 teachers from six early childhood education centers in Spain participated in the study. The authors used the Rasch model to determine the item fit and the difficulty of the items in relation to children's ability levels in this age range. The Rasch Differential Item Functioning (DIF) analysis by child age groups showed that the item difficulty differed according to the children's age and according to their levels of competence. The results of this study supported the reliability and validity of the 3M scale for assessing children's functioning in preschool classroom routines. A few items, however, were identified as needing to be reworded and more difficult items needed to be added to increase the scale difficulty level to match the performance of children with higher ability levels. The authors introduced the new and reworded items based on the results of this study and the corresponding ICF codes per item. Moreover, the authors indicate how to use the ICF Performance Qualifiers in relation to the 3M scale response categories for developing a functioning profile for the child.

Abstract
Background/Objective The aim of the study was to examine the factor structure and psychometric properties of the Spanish version of the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) in a large sample of patients with non-metastatic, resected cancer. Methods Prospective, observational, multicenter study for which 914 patients were recruited from 15 Spanish hospitals. Exploratory and confirmatory factor analyses, validity and reliability analyses were conducted. Results Factor-analytic results indicated a 4-factor structure of the Spanish version of the Mini-MAC. Three subscales have psychometric properties similar to those of Helplessness, Anxious preoccupation, and Cognitive avoidance of the original the Mini-MAC. The Fighting spirit and the Fatalism subscales were combined on the Positive attitude scale. The four factor-derived scale scores exhibited acceptable accuracy for individual measurement purposes, as well as stability over time in test-retest assessments at 6 months. Validity assessments found meaningful relations between the derived scale scores, and Brief Symptom Inventory depression and anxiety scores and Functional Assessment of Chronic Illness Therapy spiritual well-being scores. Conclusions The Spanish version of the Mini-MAC provides reliable and valid measures for patients with non-metastatic, resected cancer, and results corroborate the instrument’s cross-cultural validity.

Abstract
PURPOSE The aim of this study was to describe distinct coping styles of women newly diagnosed with breast cancer and to determine whether there is an association between those styles and the women's long-term health-related quality of life (HRQOL). METHODS Using a prospective longitudinal study design, we enrolled 101 women recently diagnosed with breast cancer in South Korea and asked them to complete a questionnaire that included the Mini-Mental Adjustment to Cancer (Mini-MAC) scale and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). RESULTS From the baseline data, we identified two coping style clusters. The first ("FS cluster") had higher scores on the fighting spirit subscale and lower scores on the helpless-hopeless and anxious preoccupation subscales (n = 52, 51.5%), while the second ("HHAP cluster") scored higher on the helpless-hopeless and anxious preoccupation subscales and lower on the fighting spirit subscale (n = 49, 48.5%). In the longitudinal analysis, the FS cluster had a better HRQOL then the HHAP cluster for 2 years after diagnosis, but the HRQOLs did not differ significantly 3 years after diagnosis. CONCLUSIONS Maladaptive coping at diagnosis may predict poor HRQOL in women with breast cancer. Regular screening of coping style and interventions to improve poor coping style should be considered for at least 2 years post initial diagnosis.

Abstract
Previous commentaries in the Formulary Evaluation section of INNOVATIONS in Pharmacy have pointed to the lack of credibility in modeled claims for cost-effectiveness and associated recommendations for pricing and access by the Institute for Clinical and Economic Review (ICER). The principal objection to ICER reports has been that their modeled claims fail the standards of normal science: they are best seen as pseudoscience. The purpose of this latest commentary is to provide a critique of the recently released ICER 2020 Value Assessment Framework (VAF). Although ICER has taken upon itself the pole position in health technology assessments and recommendations for product pricing in the US health care system, the incremental, lifetime cost-per-QALY modeling methodology should not be taken seriously. The creation of imaginary modeled worlds, built entirely from assumption, fails the demarcation test between science and pseudoscience. The ICER evidence reports are best seen as the health technology assessment equivalent of 'intelligent design' in counterpoint to 'natural selection'. It is surprising, therefore, that health care decision makers should take ICER's recommendations seriously as providing 'approximate information' for formulary decision making. What is not appreciated is that the claims made by ICER lack credibility, are impossible to evaluate and lack the ability to be replicated across treatment settings. Indeed, the models presented under the guise of a 'state of the art' value assessment were never intended to support evaluable claims. We have no idea and will never know if they are right or if they are wrong. ICER's position becomes even more untenable once the models presented are assessed in detail. Without in any way supporting the ICER methodology, it is worth noting that all too often ICER's claims for incremental QALYs in specific models are based upon what appears to be, from the limited evidence presented, a casual and ad hoc assemblage of utility scores from diverse constructs. This is a critical weakness given the role attributed by ICER to the modeled cost-per-QALY claims as central to ICERs imaginary value assessment. ICER also overlooks the fact that the utility scores it captures from the literature to populate its imaginary reference case world lack objectivity. They are ordinal rather than interval measures. To apply these manifest scores to time spent in a disease stage and then aggregate these over different disease stages is nonsensical. The critical issue is one of instrument development. The case made here is for the application of Rasch Measurement Theory (RMT) to construct a unidimensional instrument with interval properties, in this case from the needs fulfillment construct of quality of life (QoL). Unless an instrument meets RMT standards in its development, the logic of Rasch modeling to achieve fundamental measurement standards means that other scales are, by definition, ordinal. It is absurd to 'assume' they are interval. RMT is designed to create instruments to evaluate change and test hypotheses. In the absence of instruments that have RMT properties, the cost-per-QALY reference case modelling meme collapses. It is an analytical dead end. If we are to support a meaningful scientific program to discover new facts to support health care delivery and improve the lives of patients, caregivers and their families, then ICER should be put to one side.

Health Qual Life Outcomes 2017; 15:66.

Abstract
BACKGROUND The Swallowing Quality-of-Life Questionnaire (SWAL-QoL) is considered the gold standard for assessing health-related QoL in oropharyngeal dysphagia. The Dutch translation (DSWAL-QoL) and its adjusted version (aDSWAL-QoL) have been validated using classical test theory (CTT). However, these scales have not been tested against the Rasch measurement model, which is required to establish the structural validity and objectivity of the total scale and subscale scores. Thus, the purpose of this study was to examine the psychometric properties of these scales using item analysis according to the Rasch model. METHODS Item analysis with the Rasch model was performed using RUMM2030 software with previously collected data from a validation study of 108 patients. The assessment included evaluations of overall model fit, reliability, unidimensionality, threshold ordering, individual item and person fits, differential item functioning (DIF), local item dependency (LID) and targeting. RESULTS The analysis could not establish the psychometric properties of either of the scales or their subscales because they did not fit the Rasch model, and multidimensionality, disordered thresholds, DIF, and/or LID were found. The reliability and power of fit were high for the total scales (PSI = 0.93) but low for most of the subscales (PSI < 0.70). The targeting of persons and items was suboptimal. The main source of misfit was disordered thresholds for both the total scales and subscales. Based on the results of the analysis, adjustments to improve the scales were implemented as follows: disordered thresholds were rescaled, misfit items were removed and items were split for DIF. However, the multidimensionality and LID could not be resolved. The reliability and power of fit remained low for most of the subscales. CONCLUSIONS This study represents the first analyses of the DSWAL-QoL and aDSWAL-QoL with the Rasch model. Relying on the DSWAL-QoL and aDSWAL-QoL total and subscale scores to make conclusions regarding dysphagia-related HRQoL should be treated with caution before the structural validity and objectivity of both scales have been established. A larger and well-targeted sample is recommended to derive definitive conclusions about the items and scales. Solutions for the psychometric weaknesses suggested by the model and practical implications are discussed.

Abstract
The Charcot-Marie-Tooth Neuropathy Score (CMTNS) was developed as a main efficacy endpoint for application in clinical trials of Charcot-Marie-Tooth disease type 1A (CMT1A). However, the sensitivity of the CMTNS for measuring disease severity and progression in CMT1A patients has been questioned. Here, we applied a Rasch analysis in a French cohort of patients to evaluate the psychometrical properties of the CMTNS. Overall, our analysis supports the validity of the CMTNS for application to CMT1A patients though with some limitations such as certain items of the CMTNS being more suitable for moderate to severe forms of the disease, and some items being disordered. We suggest that additional items and/or categories be considered to better assess mild-to-moderate patients.

Abstract
Background: Women with breast cancer experience problems in multiple aspects of their lives, but applying effective strategies can result in enhancing their quality of life and their psychosocial adaptation to the disease. However, there is little information about the strategies that women use to cope with complications associated with their experiences following a breast cancer diagnosis. Objectives: The aim of this study was to explore the experience of coping behavior and the main strategies that women use in dealing with a breast cancer diagnosis. Methods: This study was conducted according to a qualitative phenomenological design to investigate women’s experiences in living with breast cancer and the related complications and how they cope with these issues. Purposive sampling was used for recruiting participants with breast cancer, and data collection was conducted by semi-structured, in-depth interviews with 22 patients. The transcribed interviews were analyzed using Van Manen’s thematic approach. Results: The age range of the women was 32-68. Most were married and received adjuvant therapy (i.e., mastectomy surgery and chemo-radiation). Three dominant themes that emerged from the interviews were emotional turmoil, avoidance, and logical efforts. Conclusion: The findings highlight the importance of addressing psycho-oncology intervention programs to address the unmet pyscho-social and palliative care needs of patients suffering from breast cancer.

Abstract
BACKGROUND The short version of the Problem Behaviours Assessment (PBA-s) is the recommended outcome measure for behavioural symptoms in Huntington's disease. Rasch analysis was used to further investigate the measurement limitations of the PBA-s. OBJECTIVES 1) To assess the psychometric properties of the 11 severity and frequency items within the PBA-s and 2) to determine the construct validity of using a total PBA-s score as a clinical outcome measure. METHODS PBA-s data for 517 participants from Enroll-HD were included in the Rasch analysis. Separate analyses were conducted for the severity and frequency items of the PBA-s, using RUMM2030 software. Achieving fit to the model provides supporting evidence that all items contribute to a single underlying latent trait. This property is defined as internal construct validity. RESULTS The total PBA-s severity score demonstrated several important limitations, including disordered response categories for all 11 severity items, local dependency and poor targeting. However, modifying the original five-point scoring system to a four-point system resulted in ordered response categories for seven of the severity items and achieved a good overall fit to the Rasch model. For the total PBA-s frequency score, fit to the model was not achieved even after amendments to the scoring system. CONCLUSIONS This study suggests that with reduction to a four-point scoring system, the total PBA-s severity score may be considered a valid clinical outcome measure. This study also suggests limitations in the use of a total PBA-s frequency score.

IRANIAN JOURNAL OF CANCER PREVENTION 2016; 9:e5461. [PMID: 27761211 PMCID: PMC5056016 DOI: 10.17795/ijcp-5461] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2016] [Revised: 04/09/2016] [Accepted: 08/06/2016] [Indexed: 11/25/2022]
Abstract
Background Cancer diagnosis for everybody may be perceived as crisis and breast cancer, as the most common malignancy in women, can influence their well-being and multiple aspects of their health. So understanding that how women in various contexts and communities adjust to the illness is necessary to facilitate this adjustment and improve their quality of life. Objectives The aim of this study was to: 1) identify the core components of coping strategies to adjust to the illness in Iranian women with breast cancer perspective, 2) to develop and determine psychometric properties of a native self-report instrument to assess coping behaviors and measure the degree of adjustment with the breast cancer. Methods The present exploratory mixed method study was conducted in two consecutive stages: 1) the hermeneutic phenomenological study was done to explore the life experiences of coping styles to adjust with the breast cancer using in-depth interviews with patients that lead to item generation; 2) psychometric properties (validity and reliability) of the instrument were evaluated recruiting 340 eligible women. The item pool was reduced systematically and resulted in a 49-item instrument. Results From the qualitative stage, item pool containing 78 items related to coping strategies to adjust with the breast cancer. After eliminating unwanted statements from the results, qualitative and quantitative face and content validity, the 10 factors extracted employing construct validity were: feeling of guilt, abstention-diversion, role preservation and seeking support, efforts for threat control, confronting, fear and anxiety, role wasting, maturation and growth, isolation, and fatalism. These factors accounted for the 59.1% of variance observed. The Cronbach reliability test was carried out and alpha value of 10 factors was calculated from 0.78 to 0.87 confirming all factors were internally consistent. The scale’s stability was tested using the test-retest method. Conclusions The 49-item AIMI-IBC revealed acceptable psychometric properties. This instrument provides healthcare professionals to systematically assess the coping strategies of Iranian women with breast cancer and measure the degree of adjustment with illness.

Abstract
OBJECTIVE Objective of the study was to assess the psychological state of HF patients with reduced ejection fraction (HFrEF) with regard to gender and aetiology. METHODS 758 patients with HFrEF (mean age - 64±11years, men - 79%, NYHA class III-IV - 40%, ischemic aetiology - 61%) in a prospective Polish multicenter Caps-Lock-HF study. Scores on five different self-report inventories: CISS, MHLC, GSES, BDI and modified Mini-MAC were compared between the sexes taking into account the aetiology of HFrEF. RESULTS There were differences in the CISS and BDI score between the genders - women had higher CISS (emotion- and avoidance-oriented) and BDI (general score - 14.2±8.7 vs 12.3±8.6, P<0.05; subscale - somatic score - 7.3±3.7 vs 6.1±3.7, P<0.05). In the ischemic subpopulation, women had higher BDI (general and subscales) than men. In the non-ischemic subpopulation the differences between genders were limited to CISS scale. In a multivariable analysis with demographic and clinical data female sex, NYHA class, atrial fibrillation and diabetes mellitus determined BDI score. Similarly, in the ischemic subpopulation, the female sex, NYHA class and atrial fibrillation determined the BDI, while in the non-ischemic population NYHA class was the only factor that influenced the BDI score. Adding the psychological data made a significant additional contribution to the prediction of depression status. CONCLUSIONS There are distinct differences in psychological features with regard to gender in patients with HFrEF. Women demonstrate less favourable psychological characteristics. Gender-related differences in BDI score are especially explicit in patients with ischemic aetiology of HF. The BDI score is related to psychological predisposition.

Abstract
BACKGROUND The family of KIDSCREEN instruments is the only one with trans-cultural adaptation and validation in Colombia. These validations have been performed from the classical test theory approach, which has evidenced satisfactory psychometric properties. The aim of this study was to evaluate psychometric properties of KIDSCREEN-27 children and parent-proxy versions, through Rasch analysis. METHODS The participants in the present study were two different sets of populations, 321 kids with a mean age of 12.3 (SD 2.6), 41 % 8 to 11 years old and 59 % 12 to 18 years old; and 1150 parent-proxy with an average age of 45.5 (SD 18.9). Psychometric properties were assessed using the partial credits model in the Rasch approach. Unidimensionality, fitting of person and item, response form, and differential item functioning (DIF) were measured. RESULTS The Infit MNSQ in child self-reported version that ranges between 0.71-1.76, and 0.69-1.31 in the parent-proxy version. Scores gathered on Likert forms of 5-response options, person separation was 2.08 for child self-reported version and 2.40 for parent-proxy; reliability was 0.81 and 0.85, respectively. Items reliability was 0.99 on both versions, with separations of 11.92 for child self-reported and 10.83 for parent-proxy. There was not DIF according to the variables sex and age but was present according to socioeconomic status. CONCLUSION There was a good fit for items and individuals to the Rasch model. Item separation was adecuate, and person separation improved when the response form was re-codified to four options. The presence of DIF according to socioeconomic status implies a scale's bias in the measure of HRQoL of Colombian children.

Abstract
Introduction Coping with breast cancer is an important health issue that results in adjustments to the disease in survivors. The present systematic review aims to synthesize the evidence about the coping strategies used by women who are primary breast cancer survivors to adjust to their new situations in their lives. Methods Searches were conducted using Google Scholar, PubMed, Scopus, Wiley Online Library, and PsycINFO, using the terms “breast cancer,” “breast malignancy,” “coping strategies,” “coping behaviors,” and “adjustment” from January 2000 to July 2015. Only relevant studies in English were selected at the end of the search. Only those papers were selected that focused on coping strategies/behaviors that were used by breast cancer survivors. Results Searching the electronic databases resulted in 2390 articles. Ultimately, 20 studies met the inclusion criteria of the present study and were included in the review. Two reviewers independently reviewed all relevant articles using the same inclusion criteria. The reviewers completed a quality assessment using the Newcastle–Ottawa Quality Assessment scales for observational studies. The more frequent coping strategies that patients with breast cancer used in the studies were 1) seeking social support (9 studies), 2) positive reframing and reappraisal behaviors as problem focused strategies (7 studies), 3) religious/spirituality-focused efforts (8 studies), 4) emotional expression as positive emotion-focused strategies (3 studies), and 5) avoidance and distraction as avoidance orientated strategies (6 studies). Women with different ethnicities and educational levels used different coping strategies with breast cancer, and they used different strategies in different phases of the disease. Conclusion This systematic review revealed that seeking social support and emotion-focused efforts were the main coping strategies that women with breast cancer diagnosis used, especially in the early phase of breast cancer diagnosis. This information about the coping responses of patients may be useful in designing interventional programs to assist other women in dealing with the various challenges imposed upon them by their illness.

Abstract
OBJECTIVES To internally validate a 15-item dichotomous activities of daily living (ADL) and instrumental activities of daily living (IADL) index. STUDY DESIGN AND SETTING Data were extracted from The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS). Using Rasch modeling, six aspects of the ADL/IADL scale were assessed: (1) overall fit, (2) internal consistency, (3) individual item and person fit, (4) local dependency, (5) targeting, and (6) differential item functioning (DIF) (RUMM 2030). All analyses were stratified by living situation [community-dwelling (n = 21,926) or residential care facility (n = 2,458)]. RESULTS In both settings, "eating" was the easiest activity on the scale and "performing household tasks" was the most difficult activity. However, based on the location on the logit scale, the level of difficulty for certain items varied between residential settings, suggesting summary scores are not equivalent between these settings. DIF by gender and age group was observed for several items, indicating potential measurement bias in the scale. CONCLUSION Unless adjustments are undertaken, ADL/IADL summary scores retrieved from older persons residing in the community or residential care facilities should not be directly compared. This 15-item scale is poorly targeted for a community-dwelling older population, underscoring the need for items with improved discriminative ability.

Abstract
Background Differential Item Functioning (DIF) is investigated to ensure that each item displays a consistent pattern of responses irrespective of the characteristics of the respondents. Assessing DIF helps to understand the nature of instruments, to assess the quality of a measure and to interpret results. This study aimed to examine whether the items of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) and Short-Form 12 (SF-12) exhibit DIF. Method A total of 124 outpatients diagnosed with substance dependence participated in a cross-sectional, multicenter study. In addition to the Q-LES-Q-SF and SF-12 results, demographic data such as age, sex, type of substance dependence and education level were collected. Rasch analysis was conducted (using RUMM2020 software) to assess DIF of the Q-LES-Q-SF and SF-12 items. Results For SF-12, significant age-related uniform DIF was found in two of the 12 items, and sex-related DIF was found in one of the 12 items. All of the observed DIF effects in SF-12 were found among the mental health items. Three items showed DIF on the Q-LES-Q-SF; however, the impact of DIF item on the delta score calculation for the comparisons of self-reported health status between the groups was minimal in the SF-12 and small in the Q-LES-Q-SF. Conclusion These results indicated that no major measurement bias affects the validity of the self-reported health status assessed using the Q-LES-Q-SF or SF-12. Thus, these questionnaires are largely robust measures of self-reported health status among substance users.

Abstract
INTRODUCTION Cancer diagnosis is an extremely stressful experience that has a profound impact on a patient's life. Cancer related perceived stress and complications may lead to the experience of positive psychological changes and post-traumatic growth (PTG). Since there is lack of qualitative research assessing the experience of PTG in Iranian women with breast cancer, this study aims to investigate experiences relating to PTG of Iranian women. METHODS A qualitative phenomenological approach was selected to explore the experiences of Iranian women with PTG. Data were gathered using semi-structured, in-depth interviews with 18 eligible patients, which were then transcribed and analyzed using Van Manen's thematic analysis approach. Data gathering and analyses were conducted simultaneously. In addition, MAXQDA software was used for data management. RESULTS In this study, the participants were 18 Iranian women between the ages of 31 and 65 years. Four prominent themes were extracted from the participant's statements that demonstrated the Iranian women's experiences with breast cancer-induced psychological growth and maturity: 1) appreciate of life, 2) stability, 3) spiritual prosperity, and 4) effective interaction. CONCLUSION Health care professionals are strongly recommended to design robust and timely intervention programs to improving PTG among breast cancer survivors and reduce their perceived distress resulting from cancer diagnosis.

Psychometric evaluation of the revised Illness Perception Questionnaire (IPQ-R) in cancer patients: confirmatory factor analysis and Rasch analysis. J Psychosom Res 2013; 75:556-62.

Abstract
OBJECTIVE To provide new insights into the psychometrics of the revised Illness Perception Questionnaire (IPQ-R) in cancer patients. To undertake, for the first time using data from breast, colorectal and prostate cancer patients, a confirmatory factor analysis (CFA) to assess the validity of the IPQ-R's core seven-factor structure. Also, for the first time in any illness group, to undertake Rasch analysis to explore the extent to which the IPQ-R factors form unidimensional scales, with linear measurement properties and no Differential Item Functioning (DIF). METHODS Patients with potentially curable breast, colorectal or prostate cancer, within 6months post-diagnosis, completed the IPQ-R online (N=531). CFA was conducted, including multi-sample analysis, and for each IPQ-R factor fit to the Rasch model was assessed by examining, amongst other things, item fit, DIF and unidimensionality. RESULTS The CFA showed a moderate fit of the data to the IPQ-R model, and stability across diagnosis, although fit was significantly improved following the removal of selected items. All seven factors achieved fit to the Rasch model, and exhibited unidimensionality and minimal DIF, although in most cases this was after some item rescoring and/or deletion. In both analyses, IPQ-R items 12, 18 and 24 were indicated as misfitting and removed. CONCLUSION Given the rigorous standard of Rasch measurement, and the generic nature of the IPQ-R, it stood up well to the demands of the Rasch model in this study. Importantly, the results show that with some relatively minor, pragmatic modifications the IPQ-R could possess Rasch-standard measurement in cancer patients.
