New Assessment Tools for Buying Disorder

Assessment of Criteria for Specific Internet-use Disorders (ACSID-11): Introduction of a new screening instrument capturing ICD-11 criteria for gaming disorder and other potential Internet-use disorders

Background and aims

With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder, online pornography-use disorder, social-networks-use disorder, and online gambling disorder. Due to the heterogeneity in existing instruments, we aimed to develop a consistent and economic measure of major types of (potential) specific Internet-use disorders based on ICD-11 criteria for gaming disorder.

Methods

The new 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) measures five behavioral addictions with the same set of items by following the principles of WHO's ASSIST. The ACSID-11 was administered to active Internet users (N = 985) together with an adaptation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and screeners for mental health. We used Confirmatory Factor Analyses to analyze the factor structure of ACSID-11.

Results

The assumed four-factorial structure was confirmed and was superior to the unidimensional solution. This applied to gaming disorder and to the other specific Internet-use disorders. ACSID-11 scores correlated with IGDT-10 as well as with the measures of psychological distress.

Discussion and Conclusions

The ACSID-11 seems to be suitable for the consistent assessment of (potential) specific Internet-use disorders based on ICD-11 diagnostic criteria for gaming disorder. The ACSID-11 may be a useful and economic instrument for studying various behavioral addictions with the same items and improving comparability.

[The Pathological Buying Screener: Validation in a Clinical Sample]

AIM

The aim of the study was to evaluate the psychometric properties of the 13-item Pathological Buying Screener (PBS, [1]) in a clinical sample.

METHOD

The PBS was administered to a total sample of 413 treatment-seeking patients (buying-shopping disorder n=151, gambling disorder n=59, alcohol dependency n=60, other mental disorders [anxiety, depressive, eating, somatoform disorders] n=143). Factor structure was tested in the total sample using confirmatory factor analysis (CFA), reliability was determined by means of Cronbach's α. Group comparisons were used to determine to which degree the PBS discriminates between patients with BSD and other clinical groups. The BSD-group completed a battery of other measures to explore convergent and divergent validity. A subgroup (n=29) answered the PBS before and after psychotherapy to investigate sensitivity to change. A receiver operating characteristic (ROC) curve analysis with PBS data of patients with buying-shopping disorder and those from a previous community sample 1 was performed to define a cut-off point for buying-shopping disorder.

RESULTS

The CFA showed a good model fit for both a one-factor and a two-factor structure with the subscales "loss of control/consequences" (10 items) and "excessive buying behavior" (3 items). The subscales were highly intercorrelated (r=0.92). A hierarchical regression analysis with another BSD measure as dependent variable did not indicate an own incremental validity of the subscale "excessive buying behavior". Good convergent, divergent and discriminative capacity was obtained for the PBS total score. At its recommended cut-off point of ≥29 the PBS has a sensitivity of 98% and a specificity of 94.7%.

CONCLUSION

The findings indicate good psychometric properties of the PBS and suggest that the PBS total score can be used in clinical settings.

Financial difficulties in bipolar disorder part 2: psychological correlates and a proposed psychological model

OBJECTIVES

A number of psychological variables have been shown to be prominent in bipolar disorder. However, no research has looked at the relationship between financial difficulties and psychological factors in bipolar disorder.

AIMS

This study aims to look at the relationship between financial difficulties and psychological factors in bipolar disorder.

METHOD

Fifty-four participants with diagnosis of bipolar disorder in an adult secondary care NHS mental health service completed the questionnaire pack which included measures examining financial variables including difficulty paying bills and perceived financial wellbeing. Questionnaires measured self-esteem, impulsivity, mindfulness and dysfunctional attitudes.

RESULTS

Financial difficulties cross-sectionally were related to a number of psychological variables such as mindfulness and impulsivity. Over time, the strongest effects were for compulsive spending which was increased over time by higher dependency and achievement cognitions, lower mindfulness and lower self-esteem. Poor perceived financial wellness lower self-esteem over time. A psychological model incorporating these and related findings is presented.

CONCLUSION

Psychological factors appear to be related to financial difficulties in bipolar disorder. Future research is needed to confirm the model presented here and develop interventions.
