Test Evaluation DASS - 885 Words

Test Evaluation: DASS The Depression anxiety and stress scale (DASS-21) is a 21-item quantitative measure of distress that has 3 scales- anxiety, stress and depression, each of which has 7-items (Henry Crawford, 2005). The DASS-21 is a shorter version of the full 42-item questionnaire (DASS) both of which are typically used to discriminate between the three related states of depression, anxiety and stress (Antony, Bieling, Cox, Enns, Swinson, 1998). Distinguishing between these states has proven difficult, particularly between anxiety and depression (Clark Watson, 1991a) . Many of the major scales predominantly measure the common factor of negative affectivity (Watson Clark, 1984). While the full version DASS is used in both clinical and research settings, the DASS-21 is typically used for research purposes (Lovibond, 2013). As such this paper will evaluate the empirical evidence for the validity and reliability of the DASS-21 for research purposes. Evidence for Validity The DASS-21 shares many similarities with the tripartite model of depression (Brown, Chorpita, Korotitsch, Barlow, 1997), which posits that the explanation of an affective domain requires the evaluation of both common and distinct elements (Clark Watson, 1991b). The tripartite model argues that factors of anxiety and depression can be categorised as having general distress (negative affect) as well as distinct symptoms, namely hyper-arousal, in the case of anxiety and anhedonia, in the case ofShow MoreRelatedA Comprehensive Psychological Assessment At Bradfield Hospital Mental Health2229 Words   |  9 PagesColdwell’s referral, a semi-structured clinical interview (Structured Clinical Interview for DSM–IV-TR, Axis I) will be employed which will include a Mental Status Examination, followed by the administration of the Depression Anxiety Stress Scales (DASS-42) and Social Phobia Inventory (SPIN) to assess the possibility of depression and anxiety (particularly social anxiety disorder).

For example, given that social phobia involves an intense fear of scrutiny from other people, these individuals may present with barriers to forming a collaborative alliance, such as poor social skills, extreme sensitivity to evaluations, or social avoidance (Woody Adessky, 2002).
