Prevalence of post-traumatic stress disorder and validity of the Impact of Events Scale - Revised in primary care in Zimbabwe, a non-war-affected African country.

Background: A critical step in research on the epidemiology of post-traumatic stress disorder (PTSD) in low-resource settings is the validation of brief self-reported psychometric tools available in the public domain, such as the Impact Event Scale - Revised (IES-R).

Aims: We aimed to investigate the validity of the IES-R in a primary healthcare setting in Harare, Zimbabwe.

Method: We analysed data from a survey of 264 consecutively sampled adults (mean age 38 years; 78% female).

Effectiveness of a psychological intervention delivered by general nurses for alcohol use disorders in people living with HIV in Zimbabwe: a cluster randomized controlled trial.

Introduction: There have been very few randomized clinical trials of interventions for alcohol use disorders (AUD) in people living with HIV (PLWH) in African countries. This is despite the fact that alcohol use is one of the modifiable risk factors for poor virological control in PLWH on antiretroviral therapy.

Methods: Sixteen clinic clusters in Zimbabwe were selected through stratified randomization and randomized 1: 1 to Intervention and Control arms.

Is digital cognitive behavioural therapy for insomnia effective in treating sub-threshold insomnia: a pilot RCT.

Objective/background: Many patients find cognitive behavioral therapy for insomnia (CBT-I) useful. However, it is currently unknown if those with sub-threshold insomnia also benefit. Here we assessed whether CBT-I is both feasible and acceptable in participants with sub-threshold insomnia.

Associations between exploding head syndrome and measures of sleep quality and experiences, dissociation, and well-being.

Exploding head syndrome is a sensory parasomnia characterized by the perception of loud noises and/or a sense of explosion in the head that occurs when transitioning to or from sleep. Despite receiving little attention from both researchers and clinicians, studies suggest that approximately 10%-15% of individuals have episodes, with significant levels of fear occurring in a subset of cases. Using two independent samples, we examine sleep and well-being variables associated with exploding head syndrome.

Sleep Treatment Outcome Predictors (STOP) Pilot Study: a protocol for a randomised controlled trial examining predictors of change of insomnia symptoms and associated traits following cognitive-behavioural therapy for insomnia in an unselected sample.

Introduction: Cognitive-behavioural therapy for insomnia (CBT-I) leads to insomnia symptom improvements in a substantial proportion of patients. However, not everyone responds well to this treatment, and it is unclear what determines individual differences in response. The broader aim of this work is to examine to what extent response to CBT-I is due to genetic and environmental factors.
