Abstract

Introduction

Gambling can cause negative consequences affecting finances, work/study, physical and mental health, relationships, law abidingness, and the community. Although existing measures enable investigations of gambling harms, there is still a need for a brief measure covering the full range of gambling related harms.

Methods

We validated a 7-item domain-general harm scale (DGHS-7) using data from a cross-sectional survey of United Kingdom residents reporting gambling within the last 12 months (n = 2558, 62.4% women, mean age 40.1 years (SD = 12.5)). The DGHS-7 was investigated in terms of factor structure, measurement invariance, and convergent validity with a comprehensive 72-item checklist of gambling harm, the Short Gambling Harms Screen (SGHS), and the Problem Gambling Severity Index (PGSI). Discriminative validity was checked against the Personal Wellbeing Index (PWI). Internal consistency was also calculated.

Results

Confirmatory factor analysis supported a one-factor solution (χ² = 136.991, df = 14, χ²/df = 9.785, p <.001, CFI = 0.999, RMSEA = 0.059, 90% CI [0.050, 0.068]). Measurement invariance was supported for gender and binary categorization of age and income (ΔCFI = 0.001). The DGHS-7 correlated strongly with the 72-item checklist (r_s = 0.824), the SGHS (r_s = 0.793), the PGSI (r_s = 0.768), and moderately with the PWI (r_s = -0.303). Cronbach’s alpha = 0.91 and ordinal alpha = 0.96 indicated good internal consistency.

Conclusions

Psychometric support was found for a brief measure covering all recognized domains of gambling harm. The DGHS-7 is useful for researchers needing a generic and short measure for epidemiological and other studies calling for short scales.

7项域一般赌博危害量表(DGHS-7)的验证

简介赌博会对财务、工作/学习、身心健康、人际关系、遵纪守法和社区造成负面影响。尽管现有措施可以调查赌博危害，但仍有必要制定一项涵盖所有赌博危害的简短措施。方法我们使用过去12个月内报告赌博的英国居民（n=2558，62.4%为女性，平均年龄40.1岁（SD=12.5））的横断面调查数据验证了7项领域一般伤害量表（DGHS-7），以及与赌博危害综合72项检查表、短期赌博危害筛查（SGHS）和问题赌博严重程度指数（PGSI）的收敛有效性。根据个人幸福指数（PWI）检查判别有效性。还计算了内部一致性。结果验证性因子分析支持单因子解（χ2=136.991，df=14，χ2/df=9.785，p<；.001，CFI=0.999，RMSEA=0.059，90%CI[0.050，0.068]）。性别和年龄和收入的二元分类支持测量不变性（ΔCFI=0.001），PGSI（rs=0.768）和中等程度的PWI（rs=-0.303）。Cronbachα=0.91和序数α=0.96表示良好的内部一致性。结论心理支持是一项涵盖所有公认赌博危害领域的简短措施。DGHS-7适用于需要通用且简短的流行病学和其他需要短量表的研究的研究人员。

期刊介绍： Addictive Behaviors Reports is an open-access and peer reviewed online-only journal offering an interdisciplinary forum for the publication of research in addictive behaviors. The journal accepts submissions that are scientifically sound on all forms of addictive behavior (alcohol, drugs, gambling, Internet, nicotine and technology) with a primary focus on behavioral and psychosocial research. The emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. We are particularly interested in ''non-traditional'', innovative and empirically oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research. Studies that might encourage new lines of inquiry as well as scholarly commentaries on topical issues, systematic reviews, and mini reviews are also very much encouraged. We also welcome multimedia submissions that incorporate video or audio components to better display methodology or findings.
