Depression is a common comorbid condition in Parkinson's disease (PD) and a major contributor to poor quality of life and disability. However, depression can be difficult to assess in patients with PD due to overlapping symptoms and difficulties in the assessment of depression in cognitively impaired patients. As several rating scales have been used to assess depression in PD (dPD), the Movement Disorder Society commissioned a task force to assess their clinimetric properties and make clinical recommendations regarding their use. A systematic literature review was conducted to explore the use of depression scales in PD and determine which scales should be selected for this review. The scales reviewed were the Beck Depression Inventory (BDI), Hamilton Depression Scale (Ham-D), Hospital Anxiety and Depression Scale (HADS), Zung Self-Rating Depression Scale (SDS), Geriatric Depression Scale (GDS), Montgomery-Asberg Depression Rating Scale (MADRS), Unified Parkinson's Disease Rating Scale (UPDRS) Part I, Cornell Scale for the Assessment of Depression in Dementia (CSDD), and the Center for Epidemiologic Studies Depression Scale (CES-D). Seven clinical researchers with clinical and research experience in the assessment of dPD were assigned to review the scales using a structured format. The most appropriate scale is dependent on the clinical or research goal. However, observer-rated scales are preferred if the study or clinical situation permits. For screening purposes, the HAM-D, BDI, HADS, MADRS, and GDS are valid in dPD. The CES-D and CSDD are alternative instruments that need validation in dPD. For measurement of severity of depressive symptoms, the Ham-D, MADRS, BDI, and SDS scales are recommended. Further studies are needed to validate the CSDD, which could be particularly useful for the assessment of severity of dPD in patients with comorbid dementia. To account for overlapping motor and nonmotor symptoms of depression, adjusted instrument cutoff scores may be needed for dPD, and scales to assess severity of motor symptoms (e.g., UPDRS) should also be included to help adjust for confounding factors. The HADS and the GDS include limited motor symptom assessment and may, therefore, be most useful in rating depression severity across a range of PD severity; however, these scales appear insensitive in severe depression. The complex and time-consuming task of developing a new scale to measure depression specifically for patients with PD is currently not warranted.

Relationship between Behavioral Lifestyle and Mental Health Status Evaluated Using the GHQ-28 and SDS Questionnaires in Japanese Factory Workers

2007

In order to clarify the relationships between lifestyle behaviors and mental health status in Japanese workers, the 28-item General Health Questionnaire (GHQ-28) and Zung's Self-rating Depression Scale (SDS) were administered to 254 male factory workers; further, eight of their personal health practices were surveyed using the Health Practice Index (HPI). Few studies have used the GHQ-28 and SDS simultaneously; moreover, to date, no study has included the lifestyle factors in these scales. We used these tools for the concurrent assessment of mental health status and classified the subjects into high-risk and low-risk groups. The GHQ-28 and SDS scores correlated negatively with the HPI scores. In the older age group, these scores decreased significantly corresponding to an increase in the total number of favorable lifestyle practices followed. Significant relationships were observed between the GHQ-28 subscales and the HPI. Multiple logistic regression analysis revealed that four of the eight health practices surveyed were significantly related to the mental health status in all subjects. Thus, good health practices appear to be closely associated with good mental health status. However, to establish our results, larger study populations are required for further studies in various occupational fields.

“…The Japanese version of the SASS was produced by Goto et al, who confirmed that the translated instrument was suitable for evaluating social adaptation in the Japanese population [23]. The SASS has also been validated and found to be easy to use and sensitive to changes in different social functioning areas [24,25]. We have recently reported that a significant negative correlation was obtained between SASS and the Stress and Arousal Check List (SACL), which assesses job stress in healthy workers.…”
