Reliability and validity of the dynamic risk outcome scales-short version for clients with mild intellectual disabilities or borderline intellectual functioning.

INTRODUCTION: This study investigated the reliability and validity of the dynamic risk outcome scales-short version (DROS-SV). This instrument is developed to monitor treatment progress using dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning and behavioural and/or mental health problems. METHOD: Data were collected from 264 clients who received Flexible Assertive Community Treatment (FACT), a form of intensive outpatient treatment. RESULTS: A principal component analysis showed that there were six components explaining 73.9% of the variance. Furthermore, the DROS-SV showed good internal consistency of its subscales and total score (α > 0.78). Correlating the DROS-SV with the Historical and Clinical subscales of the Historical, Clinical and Future-30 indicated convergent and divergent validity. DISCUSSION: The DROS-SV has good psychometric properties for measuring dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning in FACT teams.

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. METHOD: Confirmatory factor analysis was conducted in 148 adult clients (79% male) with mild intellectual disability or borderline intellectual functioning in a secure facility to examine internal structure validity and internal consistency reliability of the GCI-R. RESULTS: The results indicate support for the five-factor structure of the GCI-R ('Support', 'Growth', 'Repression', 'Peer interactions', and 'Physical environment'). The internal consistency reliability of its scales ranged from acceptable to good (α: .72-.87; ω: .76-.86). CONCLUSION: The GCI-R demonstrates evidence of psychometric adequacy when applied to adult clients with mild intellectual disability or borderline intellectual functioning in secure residential facilities.

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'. RESULTS: Less hostility predicted a better overall group climate, better support and atmosphere, and less repression. A positive attitude towards current treatment predicted better growth. CONCLUSION: Results indicate relationships of hostility and attitude towards current treatment with group climate. A focus on both dynamic risk factors and group climate may provide a basis for improving treatment for this target group.

The predictive value of the dynamic risk outcome scales (DROS) for recidivism in (forensic) clients with mild intellectual disabilities or borderline intellectual functioning.

BACKGROUND: The dynamic risk outcome scales (DROS) was developed to assess treatment progress of clients with mild intellectual disability or borderline intellectual functioning using dynamic risk factors. We studied the predictive value of the DROS on various classifications and severity levels of recidivism. METHOD: Data of 250 forensic clients with intellectual disabilities were linked to recidivism data from the Judicial Information Service in the Netherlands. Receiver operating characteristics (ROC) analyses were used to determine the predictive values. RESULTS: The DROS total score could not significantly predict recidivism. A DROS recidivism subscale predicted general, violent and other recidivism. These predictive values were comparable to those of a Dutch tool validated for risk assessment in the general forensic population. CONCLUSIONS: The DROS recidivism subscale predicted various classifications of recidivism better than chance. At present, the DROS appears to have no added value beyond the HKT-30 for the purpose of risk assessment.

[Feasibility of MMPI-2-RF in patients with borderline intellectual functioning]. / Toepasbaarheid van de MMPI-2-RF bij patiënten met zwakbegaafdheid.

BACKGROUND: There are few psychometrically sound diagnostic instruments available to assess personality characteristics and psychopathology in patients with borderline intellectual functioning (BIF). It is important to assess personality characteristics and psychopathology in this target group because of their high risk on psychopathology. AIM: To determine whether the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) is feasible in patients with BIF (Verbal Comprehension Index = 70-85) and psychopathology. METHOD: We examined scores on validity scales of the MMPI-2-RF of patients with BIF and compared these scores to those of a matched group of individuals with average intellectual functioning without psychopathology. RESULTS: Scores on the validity scales indicated that patients with BIF can report in a consistent and valid way about their complaints and personality characteristics. Compared to the comparison group they reported equally consistent and showed significantly more psychopathology. CONCLUSION: The MMPI-2-RF is feasible in the assessment of personality characteristics and psychopathology in patients with BIF..

[The predictive value of the Dynamic Risk Outcome Scales (DROS) for predicting recidivism in (forensic) patients with mild intellectual disabilities or borderline intellectual functioning]. / De voorspellende waarde van de Dynamic Risk Outcome Scales (DROS) voor recidive bij (forensische) patiënten met een lichte verstandelijke beperking.

BACKGROUND: The Dynamic Risk Outcome Scales (DROS) was developed to assess treatment progress of patients with mild intellectual disability (MID) or borderline intellectual functioning (BIF) and severe behavioral and/or psychiatric problems. Because of the focus on dynamic risk factors, practitioners also see this instrument as a tool for risk assessment.
AIM: To investigate the predictive value of the DROS on different classifications and severities of recidivism.
METHOD: DROS data from the routine outcome monitoring (ROM) of 250 forensic patients with MID-BIF who were discharged between 2007 and end of 2014 were linked to recidivism data from the Judicial Information Service.
RESULTS: The DROS total score predicted general, violence and sexual recidivism better than chance (AUCs > 0.58), although the effect was small. A DROS-recidivism subscale predicted general, violence and other recidivism with a medium to large effect (AUCs > 0.67). The predictive values of the DROS total score and DROS-recidivism subscale were comparable to those of the Historic, Clinical, Future (in Dutch: HKT)-30.
CONCLUSION: The DROS total score and DROS-recidivism subscale predict different classifications of recidivism better than chance. However, for risk assessment the DROS appears to have no added value to the HKT-30.

Adaption of pregnancy anxiety questionnaire-revised for all pregnant women regardless of parity: PRAQ-R2.

The 10-item Pregnancy-Related Anxiety Questionnaire-Revised (PRAQ-R) is a widely used instrument to assess and identify pregnancy-specific anxiety in nulliparous women. It has good psychometric values and predictive validity for birth and childhood outcomes. Nonetheless, the PRAQ-R is not designed for use in parous women, as particularly one item of the questionnaire is not relevant for women who gave birth before. We tested the factorial and scalar invariance of a modified PRAQ-R2 across nulliparous and parous women with an adapted item to fit both groups of pregnant women. A longitudinal study among 1144 pregnant women (n = 608 nulliparous and n = 536 parous) with two repeated measures of the PRAQ-R2 was used to test for measurement invariance of the instrument. Results show metric and scalar invariance, indicating that the PRAQ-R2 measures similar constructs on the same scale for all pregnant women at two different times during pregnancy. We conclude that the PRAQ-R2 can be used, compared, or combined in a sample of nulliparous and parous women.

The relationship between cannabis involvement and suicidal thoughts and behaviors.

BACKGROUND: In the present study, we examined the relationship between cannabis involvement and suicidal ideation (SI), plan and attempt, differentiating the latter into planned and unplanned attempt, taking into account other substance involvement and psychopathology. METHODS: We used two community-based twin samples from the Australian Twin Registry, including 9583 individuals (58.5% female, aged between 27 and 40). The Semi-Structured Assessment of the Genetics of Alcoholism (SSAGA) was used to assess cannabis involvement which was categorized into: (0) no cannabis use (reference category); (1) cannabis use only; (2) 1-2 cannabis use disorder symptoms; (3) 3 or more symptoms. Separate multinomial logistic regression analyses were conducted for SI and suicide attempt with or without a plan. Twin analyses examined the genetic overlap between cannabis involvement and SI. RESULTS: All levels of cannabis involvement were related to SI, regardless of duration (odds ratios [ORs]=1.28-2.00, p<0.01). Cannabis use and endorsing ≥3 symptoms were associated with unplanned (SANP; ORs=1.95 and 2.51 respectively, p<0.05), but not planned suicide attempts (p>0.10). Associations persisted even after controlling for other psychiatric disorders and substance involvement. Overlapping genetic (rG=0.45) and environmental (rE=0.21) factors were responsible for the covariance between cannabis involvement and SI. CONCLUSIONS: Cannabis involvement is associated, albeit modestly, with SI and unplanned suicide attempts. Such attempts are difficult to prevent and their association with cannabis use and cannabis use disorder symptoms requires further study, including in different samples and with additional attention to confounders.
