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.

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.
