Protocol for a pragmatic randomised controlled trial to evaluate effects of a brief intervention for emergency department attendees who present with moderate or high levels of non-specific psychological distress: a pilot study

Abstract

BackgroundScreening and brief intervention in the emergency department (ED) has almost exclusively focused on individuals with alcohol-use problems. The early detection of mental health problems before problems become severe will enable early intervention and support which may improve health and prevent further deterioration. The main aim of this pilot study is to provide evidence of the acceptance of a telephone intervention aimed at ED attendees with moderate or high psychological distress. This will be determined by recruitment rates, retention rates and participant satisfaction with the intervention. Secondary outcomes include whether socio-demographic variables have an impact on retention rates, and whether the intervention had any impact on psychological distress.Methods/DesignThis study will be a single-site pragmatic randomised controlled pilot study. Consenting ED attendees will be screened with the Kessler Psychological Distress Scales (K10). There will be three arms to the study: a moderate/high psychological distress group with or without intervention, and a low psychological distress group. Those with severe psychological distress will be excluded. All included participants will be followed-up at 1, 3, 6 and 12 months post-recruitment. Retention rates will be determined by successful completion of surveys at the follow-up time-points. Psychological distress will be measured by the K10 at all follow-up time-points.DiscussionThis study will provide information regarding the potential for screening and recruitment at an opportunistic hospital presentation. It will provide data for a future larger study with regard to participants accepting to be included in this study. Participant acceptability will be measured in terms of recruitment rates and retention rates measured by successful follow-ups over the following 12 months post-recruitment.Trial registrationAustralian and New Zealand Clinical Trials Registry ACTRN12614000031662.

The association between sleep quality and psychological distress among older Chinese adults: a moderated mediation model

“…With the accelerated population aging, more attention must be paid to the health issues of older adults [ 1 ]. Psychological distress would be a more practical concept in the context of comprehensive mental disorder when considering public health strategies [ 2 ]. Psychological distress is largely defined as a state of emotional suffering, typically characterized by depressive and anxiety symptoms [ 3 ], which was assessed by the Depression, Anxiety, and Stress Scale (DASS-21) in the current study [ 4 ].…”

Motivational interviewing to enhance treatment attendance in mental health settings: A systematic review and meta‐analysis

“…For people with mental illness, they are generally stereotyped as dangerous, incompetent or unable to care for themselves (Ottati, Bodenhausen, & Newman, ) and studies have found that mental disorders are still highly stigmatized (Andrade et al., ; Jorm, ; Mechanic, ; Prins et al., ; Sareen et al., ; Schomerus & Angermeyer, ), which becomes especially distressing when an individual develops a mental health problem (Corrigan, Watson, & Barr, ). Mental health problems are the most disabling illness, and medical and psychosocial treatments are not being utilized by a majority of people that could benefit (Lawrence & Fulbrook, ). Treatments have been shown to be effective in relieving mental ill‐health symptoms, but it is also important to note that there will be individuals who will not want to have any treatment, and there will also be individuals that will not recover from their symptoms (Insel & Scolnick, ).…”
