Similarities and Differences in the Functions of Nonsuicidal Self‐Injury (NSSI) and Sex as Self‐Injury (SASI)

Differences and similarities were studied in the functions of two different self‐injurious behaviors (SIB): nonsuicidal self‐injury (NSSI) and sex as self‐injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and SASI (n = 76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only. Adolescents reporting both NSSI and SASI endorsed the highest number of functions for both behaviors. Clinical implications are discussed, emphasizing the need for emotion regulation skills.     

A Systematic Review and Quality Assessment of Therapeutic Group Process Questionnaires

ABSTRACT

The aims of this study were to systematically review the literature on questionnaire-based group process measures and assess the psychometric scale development properties of these measures. A systematic search of questionnaire-based measures of group process was conducted from four databases: PsycINFO, Medline, EMBASE and AMED. A quality assessment was undertaken using established criteria. Only studies that described the development of questionnaire-based scales were included. Seventeen studies which described thirteen measures were included in the analysis. The developed list highlights a range of questionnaires that can be used by clinicians and researchers seeking to measure either “specific therapeutic group mechanisms” or “overall group experiences.” Further research should focus on developing the content validity of these scales by involving the target population during item selection and reduction.
