The Cardiff self‐injury inventory (English version): convergent validity and psychometric properties

Background and Aims: The Cardiff Self‐Injury Inventory (CSII) is a short (1 min), relatively nonintrusive, measure of previous self‐injury behaviors written in English. It measures self‐injury with suicidal intent and without such intent, covers actions versus thoughts, and has two time periods (lifetime vs recent [defined as the last 3 months]). The study aimed to examine its psychometric properties and its relationship to more well‐established measures. Methods: A UK community sample of 184 participants completed the CSII and two other measures of self‐harming (Deliberate Self‐Harm Inventory [DSHI] and Suicidal Behaviors Questionnaire–Revised [SBQ‐R]) in March 2020–May 2020. Fifty participants also repeated these measurements 1–2 weeks later. Results: The CSII showed strong psychometric properties with internal reliability of 0.87 and a test–retest of 0.82. The subscales also showed strong psychometric properties. The CSII showed strong concurrent validity to the other measures of self‐injury (SBQ‐R, r = 0.70; DSHI, r = 0.81). A factor analysis supported the idea that there are two distinct components to the overall CSII score arising due to the distinction between suicidal and nonsuicidal behaviors. Conclusion: The CSII has good psychometric properties in this population and can be used as a fast, nonintrusive, measure of different self‐injurious behaviors for clinical or research purposes

The Cardiff Self‐Injury Inventory (English version): Convergent validity and psychometric properties

Abstract Background and Aims The Cardiff Self‐Injury Inventory (CSII) is a short (1 min), relatively nonintrusive, measure of previous self‐injury behaviors written in English. It measures self‐injury with suicidal intent and without such intent, covers actions versus thoughts, and has two time periods (lifetime vs recent [defined as the last 3 months]). The study aimed to examine its psychometric properties and its relationship to more well‐established measures.

Fifty participants also repeated these measurements 1–2 weeks later. Results The CSII showed strong psychometric properties with internal reliability of 0.87 and a test–retest of 0.82. The subscales also showed strong psychometric properties. The CSII showed strong concurrent validity to the other measures of self‐injury (SBQ‐R, r = 0.70; DSHI, r = 0.81). A factor analysis supported the idea that there are two distinct components to the overall CSII score arising due to the distinction between suicidal and nonsuicidal behaviors.

Examining the relationship between neuropsychological functioning assessed during admission to a high secure psychiatric care hospital and vulnerability to long-term segregation

Purpose This paper aims to examine the relationship between neuropsychological functioning as assessed following admission to a high secure psychiatric care (HSPC) hospital and subsequent time spent in long-term segregation (LTS). Evidence from forensic populations suggests neuropsychological functioning difficulties can increase vulnerability to interpersonal violence. However, the impact of this relationship on restrictive interventions used in these settings is poorly understood. Design/methodology/approach This study quantitatively examined the neuropsychological profiles of 80 male HSPC patients as assessed during routine admission assessments, comparing data against any subsequent LTS duration during a one-year period, and a non-LTS control (n = 27). Findings Analysis found individuals who were willing and able to complete a routine neuropsychological admissions assessment spent significantly less time in LTS than those unable to complete the assessment. Performance within a test of novel problem solving (Key Search Test) was significantly worse in the LTS group than controls. Performance within a visual memory task (Immediate Recall section of the Rey Complex Figure Test) significantly correlated with LTS duration. Additional findings suggest the absence of self-reported planning difficulties as measured by a Dysexecutive Questionnaire (DEX) negatively correlated with LTS duration, while self-reported restlessness was positively correlated with LTS. Practical implications This has implications for early assessment of LTS risk and potential use of cognitive interventions to reduce the use of restrictive practices. Originality/value The results suggest some aspects of neuropsychological performance as assessed during admission to a HSPC hospital appear to be related to subsequent time spent in LTS
