Parent-Therapist Partnership Survey: Parent Feedback and Psychometric Properties.

Parents of children with disabilities are an important part of their child's special education team. However, parents often have limited involvement in school-based therapies that are provided as part of a child's Individualized Education Program. The field lacks tools to assess the domain and extent of parent needs for optimal engagement in their child's special education therapies. Study one assessed the Parent-Therapist Partnership Survey's (PTPS) (formerly known as the Needs of Parents Questionnaire -School-Based Therapy Version) measure's clarity, fit, and comprehensiveness. Study two assessed the factor structure and internal consistency. Two factors emerged - Need to Be an Informed, Engaged Member of Their Child's Team, and Need for Support and Guidance. Internal consistency was 0.93 for the overall scale. The PTPS can serve as a powerful measure to better identify opportunities to engage parents in school therapeutic goals while improving parent-provider collaboration in school-based therapies.

Pre-treatment allostatic load and metabolic dysregulation predict SSRI response in major depressive disorder: a preliminary report.

BACKGROUND: Major depressive disorder (MDD) is associated with increased allostatic load (AL; a measure of physiological costs of repeated/chronic stress-responding) and metabolic dysregulation (MetD; a measure of metabolic health and precursor to many medical illnesses). Though AL and MetD are associated with poor somatic health outcomes, little is known regarding their relationship with antidepressant-treatment outcomes. METHODS: We determined pre-treatment AL and MetD in 67 healthy controls and 34 unmedicated, medically healthy MDD subjects. Following this, MDD subjects completed 8-weeks of open-label selective serotonin reuptake inhibitor (SSRI) antidepressant treatment and were categorized as 'Responders' (⩾50% improvement in depression severity ratings) or 'Non-responders' (<50% improvement). Logistic and linear regressions were performed to determine if pre-treatment AL or MetD scores predicted SSRI-response. Secondary analyses examined cross-sectional differences between MDD and control groups. RESULTS: Pre-treatment AL and MetD scores significantly predicted continuous antidepressant response (i.e. absolute decreases in depression severity ratings) (p = 0.012 and 0.014, respectively), as well as post-treatment status as a Responder or Non-responder (p = 0.022 and 0.040, respectively), such that higher pre-treatment AL and MetD were associated with poorer SSRI-treatment outcomes. Pre-treatment AL and MetD of Responders were similar to Controls, while those of Non-responders were significantly higher than both Responders (p = 0.025 and 0.033, respectively) and Controls (p = 0.039 and 0.001, respectively). CONCLUSIONS: These preliminary findings suggest that indices of metabolic and hypothalamic-pituitary-adrenal-axis dysregulation are associated with poorer SSRI-treatment response. To our knowledge, this is the first study to demonstrate that these markers of medical disease risk also predict poorer antidepressant outcomes.

Severity of anxiety- but not depression- is associated with oxidative stress in Major Depressive Disorder.

BACKGROUND: Oxidative stress is implicated in both depression and anxiety, but it is currently unclear whether this relates to syndromal diagnoses or trans-diagnostic dimensional symptoms. We examined the relationship between oxidative stress and severity of depression and anxiety symptoms in individuals with Major Depressive Disorder (MDD). METHODS: Plasma oxidative stress markers F2-isoprostanes and oxidized glutathione (GSSG), and the antioxidant reduced glutathione (GSH), were assessed in 69 physically healthy, medication-free MDD subjects. Symptoms of anxiety and depression were assessed using the Hamilton Anxiety (HAM-A) and Hamilton Depression (HAM-D) Rating Scales. Total HAM-A and HAM-D scores, along with "core" anxiety and depression subscales, and individual HAM-D items "psychic anxiety" and "depressed mood," were related to oxidative stress markers. Analyses controlled for age, sex, BMI, and smoking. RESULTS: Total HAM-A ratings were positively associated with F2-isoprostanes (ß=.26, p=.042) and GSSG (ß=.25, p=.049), but not GSH (ß=.05, p=.711). Core anxiety severity was positively associated with F2-isoprostanes (ß=.34, p=.012) and GSSG, although this did not reach significance (ß=.24, p=.074). None of the biological markers were significantly associated with total HAM-D or core depression ratings (all p>.13). Subjects scoring high on "psychic anxiety" had elevated F2-isoprostanes (p=.030) and GSSG (p=.020). This was not seen with "depressed mood" scores (all p>.12). LIMITATIONS: We assessed peripheral oxidative markers, but their relationship to the brain is unclear. CONCLUSIONS: Oxidative stress is more closely related to anxiety than depression symptoms in MDD. This highlights the importance of relating oxidative stress to specific symptoms and could provide new insights into the biological correlates of affective disorders.
