A scoping review of the literature on the application and usefulness of the Problem Management Plus (PM+) intervention around the world

BACKGROUND

Given the high rates of common mental disorders and limited resources, task-shifting psychosocial interventions are needed to provide adequate care. One such intervention developed by the World Health Organization is Problem Management Plus (PM+).

AIMS

This review maps the evidence regarding the extent of application and usefulness of the PM+ intervention, i.e. adaptability, feasibility, effectiveness and scalability, since it was introduced in 2016.

METHOD

We conducted a scoping review of seven literature databases and grey literature from January 2015 to February 2024, to identify peer-reviewed and grey literature on PM+ around the world.

RESULTS

Out of 6739 potential records, 42 met the inclusion criteria. About 60% of the included studies were from low- and middle-income countries. Findings from pilot/feasibility trials demonstrated that PM+ is feasible, acceptable and safe. Results from definitive randomised controlled trials at short-term follow-up also suggested that PM+ is effective, with overall moderate-to-large effect sizes, in improving symptoms of common mental health problems. Although PM+ was more effective in reducing symptoms of common mental disorders, it was found to be costlier compared to usual care in the only study that evaluated its cost-effectiveness.

CONCLUSIONS

Our findings indicate that PM+, in its individual and group formats, can be adapted and effectively delivered by trained helpers to target a wide range of common mental health concerns. More effectiveness and implementation evidence is required to understand the long-term impact of PM+, its cost-effectiveness and scalability, and moderators of treatment outcomes such as gender and delivery formats.

The psychometric properties of the Swahili version of the Primary Care Post Traumatic Stress Disorder screen for DSM-5 among adults in Kenya

Background

The psychometric properties of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) are undocumented in Kenya and sub-Saharan Africa (SSA) at large. This study aimed to evaluate the psychometric properties of the Swahili version of the tool, S-PC-PTSD-5, in a community sample of adults 18 years and older drawn from Nairobi, Mombasa and Kwale counties in Kenya.

Methods

Analysis of cross-sectional data from 1431 adults from the community was conducted, examining the reliability, factorial structure, measurement invariance, and convergent and divergent validity of the interviewer-administered S-PC-PTSD-5.

Results

Out of 1431 adults who completed the S-PC-PTSD-5, 666 (46.5%) reported experiencing at least one traumatic event. Internal consistency of the S-PC-PTSD-5 was good overall, with alpha and omega values above 0.7. Confirmatory factor analysis (CFA) results indicated a one-factor structure of the S-PC-PTSD-5 for the overall sample. Multigroup CFA also demonstrated factorial invariance for sex for the one-factor structure of S-PC-PTSD-5. Scores for S-PC-PTSD-5 significantly correlated (positively) with those of generalized anxiety disorder (GAD7) and depressive symptoms (PHQ9), indicating convergent validity. S-PC-PTSD-5 scores also significantly correlated (negatively) with the WHO-5 wellbeing index, supporting divergent validity.

Conclusions

The S-PC-PTSD-5 is a reliable and valid unidimensional measure. It appears to be a valuable screening measure for probable PTSD in both urban and rural community settings in Kenya. Nonetheless, to confidently identify those who may need treatment/additional support, further research on the reliability and validity of S-PC-PTSD-5 is required, especially its diagnostic accuracy at different cutoff scores.

Mabrouk's Measure of Adolescent Optimism: Development and Validation of a New Scale of Adolescent Optimism

Several measures of adolescent optimism exist. However, none of these measures have been developed in the African setting, and only a few of the available measures have been validated for use in this setting. We aimed to develop and validate a culturally appropriate measure for this context. We employed an exploratory sequential mixed methods design using a five-step approach to tool development, comprising literature reviews, construct clarification, item development, piloting, and scale evaluation. We constructed a six-item scale, the Mabrouk's Measure of Adolescent Optimism (MMAO). In a sample of 1616 adolescents from Kenya, the MMAO demonstrated adequate internal consistency (both Cronbach's alpha and McDonald's Omega > 0.80) and test-retest reliability (ICC = 0.46). Factor analysis supported a unidimensional scale with adequate criterion and divergent validity as well as measurement invariance across sex, age (younger vs. older adolescents), residence (rural vs. urban), schooling status (in-school vs. out-of-school adolescents), and language of administration (Swahili vs. English). We report on the development and validation of a new scale of adolescent optimism that can be used to assess optimism among adolescents in Kenya and similar contexts. Preliminary evidence shows support for this new measure's reliability and validity, although additional tests are needed.
