Comparative Study
Optional thinking ability among hospital-treated deliberate self-harm patients: a 1-year follow-up study.
To investigate the association between optional thinking (the ability to generate alternative solutions to interpersonal problems) in deliberate self-harm (DSH) patients and repeated self-harm. ⋯ Poor optional thinking is associated with increased risk of repeated deliberate self-harm in those who present with a first self-harm episode. Interventions to improve optional thinking skills, delivered soon after a first DSH presentation, may be useful in preventing repetition.

Recent research suggests that preclinical Alzheimer's disease (AD) in people with Down syndrome (DS) is characterized by changes in personality/behaviour and executive dysfunction that are more prominent than deterioration in episodic memory. This study examines the relationship between executive dysfunction and the clinical and preclinical features of AD in DS. To determine the specificity of this relationship, performance on executive function (EF) measures is contrasted with performance on memory measures. ⋯ These findings provide further evidence for a specific impairment in frontal-lobe functioning in the preclinical stages of AD in DS. Implications for the assessment, diagnosis, and management of dementia in DS are discussed.

Screening for post-traumatic stress disorder (PTSD) takes place in clinical and research settings where diagnostic interviews are not feasible, and typically relies on self-report instruments like the PTSD symptom scale (PSS). Concerns have been raised about the specificity of PTSD symptoms assessed by questionnaires. This study examined whether the PSS distinguishes between patients with PTSD and those with other anxiety disorders or healthy controls. ⋯ The findings suggest that many people screened positive for PTSD may actually be suffering from another anxiety disorder.

To demonstrate the use of Rasch analysis by assessing the appropriateness of utilizing the Hospital Anxiety and Depression Scale (HADS) total score (HADS-14) as a measure of psychological distress. ⋯ The results of Rasch analysis support the use of the HADS-14 as a global measure of psychological distress. The study demonstrates the usefulness of Rasch analysis in assessing the psychometric properties of a scale and suggests that further use of this technique to assess the HADS-14 in other clinical groups is warranted.

The experience of a psychotic episode can sometimes lead to post-traumatic stress disorder (PTSD) symptoms. The objective of the research was to identify candidate predictors of such negative reactions for future prospective study. We examined six predictors identified from the PTSD and psychosis literatures in a retrospective study: a history of previous trauma, a history of previous episodes of psychosis, perceived helplessness and uncontrollability at the time of the index psychotic episode, the content of persecutory delusions at episode and the perceived presence of crisis support after the psychotic episode. ⋯ The study provides further evidence that negative reactions to psychotic episodes are relatively common. Clinicians may wish to assess for such symptoms. The study extended these findings by identifying a number of candidate psychological predictors of PTSD reactions such as perceptions of uncontrollability and absence of support. Prospective longitudinal studies are required to test the causal significance of these factors. More broadly, the findings indicate that traumatic stress in response to intra-psychic events such as delusions can be understood in similar ways to traumatic stress arising from physical traumas such as disasters.
