Expressions of psychological distress in Sierra Leone: implications for community-based prevention and response

The development of a contextually appropriate measure of psychological distress in Sierra Leone

Background

Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone.

Methods

The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS.

Results

Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale).

Conclusions

Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.

Factors contributing to emotional distress in Sierra Leone: a socio-ecological analysis

BACKGROUND

There is increasing global evidence that mental health is strongly determined by social, economic and environmental factors, and that strategic action in these areas has considerable potential for improving mental health and preventing and alleviating mental disorders. Prevention and promotion activities in mental health must address the needs prioritised by local actors. The aim of this study was to identify stressors with the potential to influence emotional wellbeing and distress within the general population of Sierra Leone, in order to contribute to an inter-sectoral public mental health approach to improving mental health within the country.

METHODOLOGY

Respondents were a convenience sample of 153 respondents (60 women, 93 men) from five districts of Sierra Leone. Using freelisting methodology, respondents were asked to respond to the open question 'What kind of problems do women/men have in your community?'. Data analysis involved consolidation of elicited problems into a single list. These were then organised thematically using an adaptation of the socio-ecological model, facilitating exploration of the interactions between problems at individual, family, community and societal levels RESULTS: Overall, respondents located problems predominantly at community and societal levels. Although few respondents identified individual-level issues, they frequently described how problems at other levels contributed to physical health difficulties and emotional distress. Women identified significantly more problems at the family level than men, particularly related to relationships with an intimate partner. Men identified significantly more problems at the societal level than women, primarily related to lack of infrastructure. Men and women were equally focused on problems related to poverty and lack of income generating opportunities.

CONCLUSION

Poverty and inability to earn an income underpinned many of the problems described at individual, family and community level. Actions to address livelihoods, together with improving infrastructure and addressing gender norms which are harmful to both men and women, are likely key to improving the wellbeing of the Sierra Leone population.
