目的:探讨香港青少年对滥用咳药水的信念。方法:应用《滥用咳药水信念量表》(Beliefs about Cough Medicine Abuse Scale-BACMAS),了解160名滥用咳药水及65名非滥用咳药水的香港青少年,对滥用咳药水的信念。结果:研究显示,此量表有高的内在一致性信度及效度(包括同证效度及构念效度)。一般而言,参加者认为滥用咳药水并不会带来很多好处,而他们亦了解滥用咳药水的危害。不过,仍然有为数不少的参加者认为,长期滥用咳药水并不会上瘾,而他们亦认为跟滥用咳药水的朋友交往并不危险。结论:此量表具有可接受的心理测量特性。青少年对滥用咳药水的自相矛盾信念,对预防滥用咳药水的工作有重要的启示。
Objective: This paper reviewed and examined the quality of all the qualitative evaluation studies indexed by two key search terms of “qualitative” and “evaluation” in the Social Work Abstracts database from 1990 to 2003 against a number of criteria typically adopted in the field of qualitative research. The review led to a dissatisfactory finding of the low quality of many qualitative evaluation studies due to their insensitivity to the following issues: philosophical basis of the study, auditability (detailed documentation of the participants and data collecting procedure), biases (acknowledgement of biases and preoccupation, and steps to deal with them), credibility or trustworthiness (triangulation, peer checking and participant verification of the findings), consistency (reliability consciousness and audit trails), and critical interpretation of the data (alternative explanations, disconfirming evidence, and limitations of the study). It was recommended that researchers be cautious when utilizing findings from the published qualitative evaluation studies; that social workers be sensitive to the issue of quality when conducting qualitative evaluation studies; that researchers be critical when judging the qualitative evaluation studies in social work; that researchers develop a clear set of guidelines for qualitative studies; that social work training institutes design qualified qualitative research courses; that a database of social work in China be established; that researchers be engaged in more qualitative studies that demonstrate high quality; that myths in qualitative research be debunked; and that adequate training for social workers on qualitative evaluation studies be provided.
