Clients with different problems are different and questionnaires are not blood tests: A template analysis of psychiatric and psychotherapy clients' experiences of the CORE‐OM

Rigorous idiography: Exploring subjective and idiographic data with rigorous methods-The method of derangements

Psychological research often seeks general rules applying across individuals, an aim that is in tension with examining that which is unique to any individual. There are general statistical regularities across individuals' subjective self-report which enable much psychology and psychotherapy research to combine data from self-report questionnaire responses with statistical and psychometric methods to create a fundamental part of Cronbach and Meehl's foundational nomological networks of validity. However, these methods only apply when most participants answer the same questions on measures creating nomothetic data and this has led to a neglect of idiographic data. This paper reviews a method of analysis of idiographic data, of "rigorous idiography": the method of derangements. This is a remarkably simple statistical test of whether purely idiographic data convey reliable information. We show how the method appeared to become stuck in a bibliometric backwater but we expand on its potential for research and practise and hope it will be taken up and used correctly and more widely.

Measurement properties of the Swedish clinical outcomes in routine evaluation outcome measures (CORE-OM): Rasch analysis and short version for depressed and anxious out-patients in a multicultural area

Introduction

The Swedish version of the patient-reported Clinical Outcomes in Routine Evaluation Outcome Measures (CORE-OM) has demonstrated high reliability and acceptable convergent validity in explanatory factor analyses. However, the fundamental scale properties have not yet been validated according to item response theory. The aim of this study was to analyze the measurement properties of the Swedish CORE-OM in a cohort of psychiatric out-patients with depression and anxiety in a multicultural area and to explore combinations of items based on shorter versions of the scale (CORE-10, CORE-6D) to improve measurement properties.

Methods

Data from CORE-OM assessments of 337 patients were analyzed using Rasch analysis. The patients had a mean age of 30 ± 14 years, the majority were women (72%). Requirements for measurement properties were checked: overall model fit, item fit residuals, targeting, internal consistency, differential item functioning and thresholds. Sensitivity to change was also analyzed.

Results

The CORE-OM showed high internal consistency (person separation index = 0.947) and adequate targeting, but there was overall model misfit (item trait interaction χ² = 917.53, p < 0.001), indication of local dependency, and differential item functioning in 9 items. The risk items showed problems with disordered thresholds. The emotional component of the shorter CORE-6D showed the best fit for our sample. Adding 3 items to include depressive and trauma-related content resulted in a unidimensional 8-item set with acceptable reliability, model fit, targeting and sensitivity to change.

Conclusion

For out-patients with diagnosed depression or anxiety in a multicultural area, the Swedish CORE-OM showed high internal consistency, but also validity problems. Based on the shorter CORE-6D version, a unidimensional 8-item set could be an alternative brief measure of psychological distress for this population, but further validity studies are required. Qualitative studies exploring the CORE-OM items in non-native speakers are also warranted.

A case series study of an innovative community-based brief psychological model for men in suicidal crisis

OBJECTIVES

To conduct a 1-year evaluation of James' Place, a suicidal crisis centre delivering a clinical intervention in a community setting.

DESIGN

A case series study, following men entering the service during the first year of operation.

PARTICIPANTS

Men experiencing a suicidal crisis referred to the service (N = 265), with N = 176 going on to engage in therapy.

INTERVENTION

The James' Place Model is a therapeutic intervention offered to men who are in a suicidal crisis. Trained therapists provide a range of therapeutic approaches and interventions, focusing on decreasing suicidal distress and supporting men to develop resilience and coping strategies.

MAIN OUTCOME MEASURES

CORE-34 Clinical Outcome Measure (CORE-OM).

RESULTS

For all subscales of the CORE-OM there was a significant reduction in mean scores between assessment and discharge (p < 0.001), with all outcomes demonstrating a large effect size. All reductions illustrated a clinically significant change or a reliable change.

CONCLUSIONS

Our results support the use of the James' Place Model for men in suicidal distress to aid in potentially preventing suicides in this high-risk group of the population.HighlightsEvaluates a brief psychological clinical intervention delivered in the community.Model effectively reduces suicide risk and findings can inform future services.Accessed men receiving an innovative intervention at the time of suicidal crisis.

"Infeliz" or "Triste": A Paradigm for Mixed Methods Exploration of Outcome Measures Adaptation Across Language Variants

The literature on measure translation tends to hold, overtly or covertly, a questionable assumption about the possibility of exact translation and almost completely ignores issues of within language variation. Equally, psychometric methods used to assess cross-cultural validity after translation focus on large sample tests of cross-sectional measurement invariance. Such invariance is often not found and is of dubious pertinence to change/outcome measures usually used in psychotherapy research. We present a sequential process of three substudies using quantitative and qualitative procedures to explore whether an outcome measure needs to be changed when used across language variation. Qualitative data confirmed that an item was not ideal in the new context. However, quantitative exploration showed that, although statistically significant and affected by gender and item order, the impact of changing the item in the overall score was small, allowing retention of the existing Spanish translation. We argue that the myth of perfect translation and over-reliance on large-sample psychometric testing pursuing measurement invariance limit exploration of language effects. We recommend that these be used in the companion of user-based, sequential, mixed-method exploration to support the development of a richer field of understanding of outcomes and change self-report measures across languages and cultures and both across and within languages.

A Case Series Study of Help-Seeking among Younger and Older Men in Suicidal Crisis

Due to the continuing high suicide rates among young men, there is a need to understand help-seeking behaviour and engagement with tailored suicide prevention interventions. The aim of this study was to compare help-seeking among younger and older men who attended a therapeutic centre for men in a suicidal crisis. In this case series study, data were collected from 546 men who were referred into a community-based therapeutic service in North West England. Of the 546 men, 337 (52%) received therapy; 161 (48%) were aged between 18 and 30 years (mean age 24 years, SD = 3.4). Analyses included baseline differences, symptom trajectories for the CORE-34 Clinical Outcome Measure (CORE-OM), and engagement with the therapy. For the CORE-OM, there was a clinically significant reduction in mean scores between assessment and discharge (p < 0.001) for both younger and older men. At initial assessment, younger men were less affected by entrapment (46% vs. 62%; p = 0.02), defeat (33% vs. 52%; p = 0.01), not engaging in new goals (38% vs. 47%; p = 0.02), and positive attitudes towards suicide (14% vs. 18%; p = 0.001) than older men. At discharge assessment, older men were significantly more likely to have an absence of positive future thinking (15% vs. 8%; p = 0.03), have less social support (45% vs. 33%; p = 0.02), and feelings of entrapment (17% vs. 14%; p = 0.02) than younger men. Future research needs to assess the long-term effects of help-seeking using a brief psychological intervention for young men in order to understand whether the effects of the therapy are sustainable over a period of time following discharge from the service.
