Psychometric analysis of the Group Climate Inventory-Revised in adults with mild intellectual disability or borderline intellectual functioning in a secure residential facility.

Background: In secure residential facilities, group climate perceptions of clients with mild intellectual disability or borderline intellectual functioning are systematically assessed for quality improvement. A valid and reliable measure may ensure that this process is consistent. The Group Climate Inventory-Revised (GCI-R) is a new measure to assess group climate perceptions.

Measurement invariance of the group climate inventory across adults with and without mild intellectual disability in secure residential facilities.

Background: The Group Climate Inventory (GCI) was tested for measurement invariance across 332 adults with and 225 adults without mild intellectual disabilities in Dutch forensic treatment, and for latent mean differences on its Support, Growth, Repression, and Atmosphere subscales.

Method: Multigroup confirmatory factor analysis was used to evaluate the configural, threshold, and loading and threshold invariance of the GCI across both groups, and to compare group latent means on each subscale.

Results: Measurement invariance was found across groups.

Relationships between dynamic risk factors for externalising problem behaviour and group climate in adults with mild intellectual disability in forensic treatment.

Background: Relationships between dynamic risk factors for externalising problem behaviour and group climate were investigated in 151 adult in-patients with mild intellectual disability or borderline intellectual functioning in a Dutch secure residential facility.

Method: Regression analysis was used to predict total group climate score and Support, Growth, Repression, and Atmosphere subscales of the 'Group Climate Inventory'. Predictor variables were Coping Skills, Attitude towards current treatment, Hostility, and Criminogenic attitudes subscales of the 'Dynamic Risk Outcome Scales'.

Group climate, aggressive incidents and coercion in a secure forensic setting for individuals with mild intellectual disability or borderline intellectual functioning: A multilevel study.

Background: This study examines associations between group climate, aggressive incidents and coercive measures in adults with mild intellectual disability or borderline intellectual functioning (MID-BIF) of a secure forensic setting.

Method: Participants (N = 248) were interviewed about their perception of group climate utilizing the Group Climate Instrument. Data on aggressive incidents and coercive measures were retrieved from the facilities' electronic database.

Psychometric properties of the Group Climate Instrument (GCI) in individuals with mild intellectual disability or borderline intellectual functioning.

Background: This study examined the psychometric properties of the Group Climate Instrument (GCI) in a sample of N = 189 adults (79% men) with mild intellectual disability or borderline intellectual functioning who were residents of a treatment facility in the Netherlands.

Method: Construct validity of the GCI was examined by means of confirmatory factor analysis. Also, reliability and convergent validity of the GCI were examined.
