“…Corrected item-total correlations from our study suggest good homogeneity. Interestingly, sleep and appetite/weight items show the poorest performance, a finding consistent with the results of previous studies (Bernstein et al, 2009;Rush et al, 2003Rush et al, , 2006aTrivedi et al, 2004).…”

“…Previous works with the original and other languages versions of the QIDS-SR 16 already demonstrated satisfactory internal consistency and homogeneity (Bernstein et al, 2009(Bernstein et al, , 2010bCameron et al, 2013;Liu et al, 2013;Rush et al, 2003Rush et al, , 2006aTrivedi et al, 2004;Yeung et al, 2012). Our findings are in the upper bound of the range of previously reported alpha coefficients (0.70-0.89), indicating good internal consistency.…”

“…A Principal Components Analysis, with Varimax rotation, and a Parallel analysis (Bernstein et al, 2009;Horn, 1965;Humphreys and Montanelli, 1975) were used to define the dimensionality of the SHAPS. In a unidimensional scale, the observed eigenvalue of the first principal component should exceed the eigenvalue of the first randomly generated principal component (using Parallel analysis), but the reverse should be the case of all subsequent eigenvalues.…”

Anhedonia or inability to experience pleasure not only is a core symptom of major depressive disorder (MDD), but also is identified as an important component of the positive valence system in the NIMH Research Domain Criteria. The Snaith-Hamilton Pleasure Scale (SHAPS) has been developed for the assessment of hedonic experience or positive valence, but has not been well-studied in depressed outpatient populations. The current study examined the reliability and validity of the SHAPS using a sample of adult outpatients with treatment resistant MDD. Data for the current study were obtained from 122 adult outpatients with a diagnosis of MDD and non-response to adequate treatment with an SSRI and who participated in Project TReatment with Exercise Augmentation for Depression (TREAD). A Principal Components Analysis was used to define the dimensionality of the SHAPS. Convergent and discriminant validity were evaluated via correlations of the SHAPS total score with "gold standard" measures of depression severity and quality of life. The SHAPS was found to have high internal consistency (Cronbach's coefficient α = .82). A Principal Components Analysis suggests that the SHAPS is mainly "unidimensional" and limited to hedonic experience among adult outpatients with MDD. Convergent and discriminant validity were assessed by examining the Spearman rank-order correlation coefficient between the SHAPS total score and the HRSD17 (rs = 0.22, p < .03), IDS-C30 (rs = 0.26, p < .01), IDS-SR30 (rs = 0.23, p < .02), QIDS-C16 (rs = 0.22, p < .03), QIDS-SR16 (rs = 0.17, p < .10), QLES-Q (rs = -0.32, p < .002), and the pleasure/enjoyment item (sub-item 21) of the IDS-C (rs = 0.44, p < .0001) and IDS-SR (rs = 0.38, p < .0002). The self-administered SHAPS showed modest sensitivity (76%) and specificity (54%) with the self-administered pleasure/enjoyment single item (sub-item 21) of IDS-SR30. The current study shows that the SHAPS is a reliable and valid instrument to assess hedonic experience or positive valence in adult outpatients with MDD and provides a broader assessment of this important domain.

“…A strength of the QIDS-SR is its ability to assess current depressive symptoms. The QIDS-SR assesses core symptoms of MDD in the DSM-IV-TR and is strongly associated with scores on clinician-rated depression instruments (Rush et al, 2003) and structured diagnostic interviews (Bernstein et al, 2009;Doraiswamy et al, 2010), and has been used in large clinical studies (Kessler et al, 2003;Rush et al, 2006b;Trivedi et al, 2006). However, if the hippocampal volume changes occur over long periods then the study is limited by only comparing a slowly changing brain change with a current measure of depression.…”

Hippocampal atrophy is reported in major depressive disorder (MDD). However, sample sizes were generally modest, and participant characteristics, including age, differed between studies. This study used a community sample to examine relationships between current depressive symptom severity and hippocampal volume across the adult lifespan. A total of 1936 adults with magnetic resonance images of the brain and Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) scores were included. Brain volumes were quantified using the FSL program. Multiple linear regressions were performed using left, right, and total hippocampal volume as criterion variables, and predictor variables of QIDS-SR total, total brain volume, age, gender, education, psychotropic medications, alcohol use, and race/ethnicity. Post hoc analyses were conducted in participants with QIDS-SR scores X11 (moderate or greater depressive symptom severity) and o11, and older and younger adults. In the primary analysis (sample as a whole) QIDS-SR was inversely associated with total hippocampal volume (b ¼ À 0.044, p ¼ 0.032, (CI À 0.019 to À 0.001)) but not with left or right hippocampal volume evaluated individually. In participants with QIDS-SR scores of o11, hippocampal volumes were not associated with QIDS-SR scores. In those with QIDS-SR scores X11 total, right, and left hippocampal volumes were modestly, but significantly, associated with QIDS-SR scores. The association between QIDS-SR scores and the hippocampal volume was much stronger in older persons. Findings suggest smaller hippocampal volumes among those with greater reported depressive symptom severity-an association that is strongest in people with at least moderate depressive symptom levels.
