An attempt to employ the Zung Self-Rating Depression Scale as a 'lab test' to trigger follow-up in ambulatory oncology clinics: Criterion validity and detection
ABSTRACT We examined issues of criterion validity and detection of depression employing the Zung Self-Rating Depression Scale (ZSDS) as a "lab test" to trigger follow-up interviews of ambulatory oncology patients by oncology staff and the possibility of subsequent algorithm-based antidepressant treatment. Sixty oncology patients were screened with the ZSDS and then interviewed using the Mini-International Neuropsychiatric Interview (MINI). We examined the sensitivity and specificity of various cutoffs on the ZSDS and a briefer version, the Brief Zung Self-Rating Depression Scale (BZSDS) as they predicted results of the MINI, which was used as the criterion. Mean age of patients was 58.3 years (SD = 11.9). Thirty-two were female (53.3%) and 28 were male (46.7%). The correlation of the ZSDS (r = -0.66, P <.0001) and BZSDS (r = -0.57, P <.0001) with the MINI overall suggested acceptable levels of criterion validity. Additionally, we examined various cutoff scores on the ZSDS and BZSDS to explore the false negative and false positive rates that are associated with each. For example, using the mild cutoff on the Zung (score > 48) to determine depression or adjustment disorder, 14 false negatives and 2 false positives were found. When the more stringent moderate cutoff (score > 56) was used, 25 false negatives and 0 false positives were found. Oncology staff can utilize such data to make decisions about where to set cut-offs that trigger follow-up based on the amount of error that is allowable in their attempts to identify depressive symptoms in their patients. We discuss that such decisions might be based on many factors including the resources available in a particular site for follow-up or the comfort of particular oncologists and nurses managing and prescribing psychotropic medications, or in providing supportive counseling.

- "It is a self-report scale comprising 20 statements related to depression, with half being formulated in positive terms and half in negative terms. The scores obtained are interpreted according to the following categories: normal (not depressed, raw score b 40), mild (raw score 40–47), moderate (raw score 48–55) and severe (raw score N 55) (Passik et al., 2001).

ABSTRACT: The most important factor which predisposes young people to suicide is depression, although protective factors such as self-esteem, emotional adaptation and social support may reduce the probability of suicidal ideation and suicide attempts. Several studies have indicated an elevated risk of suicide for health-related professions. Little is known, however, about the relationship between perceived emotional intelligence and suicide risk among nursing students. The main goals were to determine the prevalence of suicide risk in a sample of nursing students, to examine the relationship between suicide risk and perceived emotional intelligence, depression, trait anxiety and self-esteem, and to identify any gender differences in relation to these variables. Cross-sectional study of nursing students (n=93) who completed self-report measures of perceived emotional intelligence (Trait Meta-Mood Scale, which evaluates three dimensions: emotional attention, clarity and repair), suicide risk (Plutchik Suicide Risk Scale), self-esteem (Rosenberg Self-esteem Scale), depression (Zung Self-Rating Depression Scale) and anxiety (Trait scale of the State-Trait Anxiety Inventory). Linear regression analysis confirmed that depression and emotional attention are significant predictors of suicidal ideation. Moreover, suicide risk showed a significant negative association with self-esteem and with emotional clarity and repair. Gender differences were only observed in relation to depression, on which women scored significantly higher. Overall, 14% of the students were considered to present a substantial suicide risk. The findings suggest that interventions to prevent suicidal ideation among nursing students should include strategies to detect mood disorders (especially depression) and to improve emotional coping skills. In line with previous research the results indicate that high scores on emotional attention are linked to heightened emotional susceptibility and an increased risk of suicide. The identification and prevention of factors associated with suicidal behaviour in nursing students should be regarded as a priority.Nurse education today 07/2013; 34:520-525.

- "Esta versão resumida foi projetada para maximizar a confiabilidade da identificação dos sintomas cognitivos da depressão (por exemplo, anedonia,concentração, disforia, desesperança ), ao eliminar os sintomas somáticos que muitas vezes são confundidos com o tratamento do câncer – por exemplo, fadiga, alterações do apetite e insônia (Passik et al., 2001). Os itens são respondidos por meio de uma escala de 1 a 4. Escores entre 22 a 32 são indicativos de depressão com gravidade leve, entre 33 a 38 com gravidade moderada e entre 39 a 44 com gravidade severa (Passik et al., 2001). No atual estudo, o coeficiente alfa de Cronbach foi de 0,82, valor similar ao relatado (0,84) por Dugan et al. (1998) em pacientes com câncer. "
ABSTRACT: This study investigated the sleep quality of women with breast cancer and their relationship with quality of life and depression. Fifty women with breast cancer (clinical group) and a control group of other 50 women without the disease answered a clinical-demographic questionnaire and the Pittsburgh Sleep Quality Index. The clinical group also completed the Quality of Life Cancer-Survivor and the Brief Zung Self-Rating Depression Scale questionnaires. It was found that women with breast cancer had significantly more complaints of nocturia, heat and nighttime awakenings. The clinical group with poor quality of sleep reported impaired quality of life and more symptoms of depression. In general terms, sleep quality in women with breast cancer can predict their quality of life and psychological well-being.Psicologia Reflexão e Crítica 12/2011; 25(3):506-513.

- "The sum of the 20 items, after transposing the 10 items that are reverse-scored, produces a raw score of 20–80. Previous studies pointed out that scores are not meant to offer strict diagnostic guidelines but rather denote levels of depressive symptoms that might be clinically significant (Passik et al. 2001; Zung 1965, 1967). The Korean version of SDS was used in this study and has high internal consistency (i.e., Cronbach alpha for the SDS=0.79; Lee and Song 1991). "
ABSTRACT: This paper reports the underlying structure of the demographic and clinical characteristics of level 3 (i.e., pathological) Korean casino gamblers. The participants reported their gambling behavior and clinical characteristics known to be associated with gambling problems (e.g., alcohol use problems, eating disorders, depression, anxiety, and impulsivity). Factor analysis identified three domains underlying level 3 gambling: emotional instability, reward sensitivity/drive, and behavioral expression. A cluster analysis identified that the “Reward sensitivity/drive” and the “Behavioral expression” were determinant factors for characterizing clusters, while the “Emotional instability” was considered as a general factor contributing to level 3 gambling. Discriminant analysis using the composite values correctly classified 95% of the participants among three clusters. These results suggest that Korean level 3 gambling is not a unidimensional disorder, but instead a multidimensional phenomenon.International Journal of Mental Health and Addiction 10/2007; 6(4):551-563.
