Associations between childhood biomedical factors,maternal smoking,personality traits,Body and Mass Index and the prevalence of asthma in adulthood

Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.     

Enhancing treatment effectiveness through social modelling: A pilot study

Objective: Medical treatments take place in social contexts; however, little research has investigated how social modelling might influence treatment outcomes. This experimental pilot study investigated social modelling of treatment effectiveness and placebo treatment outcomes.

Design: Fifty-nine participants took part in the study, ostensibly examining the use of beta-blockers (actually placebos) for examination anxiety. Participants were randomly assigned to observe a female confederate report positive treatment effects (reduced heart rate, relaxed, calm) or feeling no different.

Main outcome measures: Heart rate, anxiety and blood pressure were assessed, as were symptoms and attributed side effects.

Results: Heart rate decreased significantly more in the social modelling compared to control condition, p = .027 (d = .63), and there were trends towards effects in the same direction for both anxiety, p = .097 (d = .46), and systolic blood pressure, p = .077 (d = .51). Significant pre-post placebo differences in heart rate, anxiety and diastolic blood pressure were found in the social modelling group, ps < .007 (ds = .77–1.37), but not the control condition, ps > .28 (ds = .09–.59).

Conclusions: Social observation of medication effectiveness enhanced placebo effectiveness in heart rate, and showed a trend towards enhancing treatment effectiveness in both anxiety and systolic blood pressure. Social modelling may have utility in enhancing the effectiveness of many active medical treatments.     

Disease controllability moderates the effect of coping efficacy on positive affect

Objective: This study aims to test experimentally whether coping strategies (approach- vs. avoidance-oriented coping) have differential effects under conditions of high or low stressor controllability.

Design: Undergraduates (62 women, 30 men) participated in a 2 × 2 experimental study where they were introduced to a fictitious disease (tisomerase enzyme deficiency) said to be either controllable or uncontrollable and an approach- or avoidance-oriented coping behaviour induction.

Main Outcome Measures: Changes in positive and negative affect.

Results: A significant disease control x coping interaction on positive affect (f² = .07, p = .011) revealed that approach-coping condition participants had higher positive affect than avoidance-coping condition participants when disease control was high (d = .94, p = .003), but not when it was low (d = .11, p = .93). The experimental conditions did not significantly influence negative affect.

Conclusion: Results demonstrate that disease control moderates the salubrious effects of approach-oriented coping on positive affect. For controllable, but not uncontrollable, health stressors, promoting problem-focused approach-oriented coping strategies may be recommended.     

Rethinking barriers: a novel conceptualization of exercise barriers in cancer survivors

Previous research suggests different types of barriers may demonstrate different relationships with intention to engage in health behaviors. This study explored global, practical, and health-related barriers’ relationships with exercise intention and behavior among cancer survivors. The mediating role of intention in the barriers-behavior relationships was also evaluated. Cancer survivors (N = 152) completed self-report measures of exercise barriers, intention, and behavior at baseline and of exercise behavior two months later. Global barriers were negatively related (p < .01) and practical and health-related barriers were unrelated (ps ≥ .07) to exercise intention. Global and practical barriers were negatively related (ps < .01) and health-related barriers were unrelated (p = .48) to subsequent exercise behavior. Exercise intention did not mediate any barriers-behavior relationships. Results suggest that global and practical barriers should be targeted in barriers reduction interventions and highlight the intention-behavior gap problem. Future research should explore multidimensionality of barriers for other health behaviors.     

Positive affect mediates the relationships between resilience,social support and posttraumatic growth of women with infertility

This study aims to explore the relationship between resilience, social support, positive affect and posttraumatic growth among Chinese women with infertility, and to examine the mediating role of positive affect. A convenience sample of 1733 women diagnosed with infertility was recruited from the infertility outpatient clinics at three reproductive hospitals in Shandong Province of China between May 2015 and April 2016. They completed a background questionnaire, the Posttraumatic Growth Inventory, the Perceived Social Support Questionnaire, the Connor-Davidson Resilience Scale, the Positive and Negative Affect Schedule. Individuals reported high levels of PTG (M = 64.81; SD = 16.20). Perceived social support (β = .11, p < .001), resilience (β = .18, p < .001) and positive affect (β = .46, p < .001) were related to PTG. Positive affect may play a mediating role in the relationships between resilience (.125, .201, p < .001), social support (.055, .121, p < .001) and PTG. This study examines the effects of resilience, social support, and positive affect on PTG among Chinese infertile women. Wherein, positive affect may play a mediating role in the relationships between resilience, social support and PTG.     

The impact of smoking cues in antismoking messages among intermittent and light smokers

Objective: Based on the Limited Capacity Model of Motivated Mediated Message Processing, this study explored the effects of smoking cues in antismoking Public Service Announcements (PSAs) on message processing among intermittent/light smokers and nonsmokers.

Method: A 2 (smoking cues: present vs. absent) × 2 (smoking status: smokers vs. nonsmokers) mixed experimental design was conducted. Self-report measures and two physiological measures including skin conductance and heart rate were examined.

Results: Messages with smoking cues generated higher levels of arousal (F = 4.57, p = .04), attention (F = 2.51, p = .04), positive message evaluation (F = 28.70, p < .001) and less intent to smoke (F = 26.60, p < .001). Intermittent and light smokers had much stronger reactions to messages containing tobacco-related visuals, including arousal (F = 4.10, p = .04), perceived ad effectiveness (F = 9.24, p = .03) and intent to smoke (F = 22.98, p < .001).

Implication: The antismoking arguments may have suppressed cue-induced smoking urges, which dampened negative persuasion outcomes. Limitations included the restricted generalisability and the focus on short-term effect. Future research may use a random sample of PSAs with a general population.     

Predictors of improvement in an open-trial multisite evaluation of emotion regulation group therapy

Emotion regulation group therapy (ERGT) is a novel treatment specifically targeting deliberate non-suicidal self-harm (DSH) in individuals with borderline personality disorder (BPD). Identifying robust predictors of positive response to ERGT could aid clinicians in treatment selection; however, to date, only one such study has been conducted. Thus, we aimed to replicate previously identified predictors of treatment response to ERGT by investigating demographic, clinical, and diagnostic predictors in 95 women with BPD or subclinical BPD who had participated in an open-trial evaluation of ERGT. Outcomes evaluated were frequency of DSH and emotion dysregulation. Assessments were conducted at pretreatment, post-treatment, and 6-month follow-up. Multilevel mixed linear models and multilevel negative binomial generalized estimated equations were used to identify significant interactions between the predictors and outcomes.

We found that greater pretreatment DSH frequency was associated with greater improvements in DSH during treatment (b = 0.998, SE = 0.00, p = 0.03) and follow-up (b = 0.997, SE = 0.00, p < 0.01) and that greater BPD severity was associated with greater improvements in DSH during treatment (b = 0.84, SE = 0.06, p = 0.02) and in emotion dysregulation at follow-up (b = ?3.05, SE = 1.47, p = 0.04). Co-occurring disorders were associated with poorer treatment response during follow-up. Results were generally consistent with a previous study of the predictors of response to ERGT. The findings provide further support for the utility of this treatment across a range of BPD patients, including patients with severe DSH and BPD.     

Racial exclusion causes acute cortisol release among emerging-adult African Americans: The role of reduced perceived control

ABSTRACT

Racial discrimination contributes to stress-related health disparities among African Americans, but less is known about the acute effects of racial exclusion on the hypo-pituitary-adrenocortical response and psychological mediators. Participants were 276 Black/African American emerging-adults (54% female; M _age = 21.74, SD = 2.21) who were randomly assigned to be excluded or included by White peers via the game Cyberball. Racial exclusion (vs. inclusion) predicted: greater negative affect (F(1, 276) = 104.885, p < .0001), lower perceived control (F(1, 276) = 205.523, p < .0001), and greater cortisol release (F(1, 274) = 4.575, p = .033). Racial exclusion’s impact on cortisol release was mediated by lower perceived control (95% CI: .027, .112), but not negative affect (?.041, .013). These findings suggest that racial exclusion contributes to acute cortisol release, and that reduced perceived control is a consequence of racial discrimination that has important implications for the health of those who experience discrimination.     

Predictors of psychological outcomes in a longitudinal study of Latina breast cancer survivors

Objective: This study sought to investigate the unique contributions of socio-ecological, cultural and cancer treatment-related factors in predicting depressive symptoms and cancer-specific distress among Latinas. Design: Participants were 140 English or Spanish-speaking Latinas (M_age = 50.6) with non-metastatic breast cancer who were assessed within two years of diagnosis (Time 1) and three months later (Time 2).

Main Measures: Hierarchical regression analyses identified predictors of depressive symptoms and cancer-specific distress at Time 1 and 2.

Results: Most women scored above the clinical cut-offs for depressive symptoms and cancer-specific distress. After adjusting for socio-ecological factors, greater Latino enculturation, measured by Latino ethnic identity, was significantly associated with greater cancer-specific distress at Time 1 (β = .20, p < .05). A significant interaction (p < .01) revealed that among women high on Latino identity, lower English language use was associated with more cancer-specific distress than higher English language use. After adjusting for socio-ecological factors, greater satisfaction with surgical treatment predicted improved depressive symptoms and cancer-specific distress across time (β_s range from ?.31 to ?.18, p_s < .01).

Conclusions: Findings elucidate the complex relationship between culture and psychological outcomes in the breast cancer context and suggest that treatment satisfaction might be an important intervention target for Latinas.     

Testing social-cognitive mediators for objective estimates of physical activity from the Healthy Eating and Active Living for Diabetes in Primary Care Networks (HEALD-PCN) study

Objective: More evidence from prospective studies is needed to determine ‘if’ and ‘how’ social cognitive constructs mediate behaviour change. In a longitudinal study, we aimed to examine potential social cognitive mediators of objectively measured physical activity (PA) behaviour among people with type 2 diabetes (T2D) who participated in a six-month PA intervention. Methods: All participants from the proven effective Healthy Eating and Active Living for Diabetes in Primary Care Networks trial were included for this secondary analysis. Change in pedometer-derived daily step counts (baseline to six months) was the outcome of interest. Primary constructs of interest were from Social Cognitive Theory, however constructs from and Theory of Planned Behaviour were also tested in a mediating variable framework using a product-of-coefficients test. Results: The sample (N = 198) had a mean age of 59.5 (SD 8.3) years, haemoglobin A1c 6.8% (SD 1.1), 50% women, BMI 33.6 kg/m² (SD 6.5), systolic pressure 125.6 mmHg (SD 16.2) and average daily steps were 5879 (SD 3130). Daily pedometer-determined steps increased for the intervention group compared to usual care control at six-months (1481 [SD 2631] vs. 336 [SD 2712]; adjusted p = .002). There was a significant action theory test effect for ‘planning’ (A = .21, SE = .10, p = .037), and significant conceptual theory test results for ‘subjective norms’ (B = 657, SE = 312, p = .037) and ‘cons’ (B = ?664, SE = 270, p = .015). None of the constructs satisfied the criteria for mediation. Conclusions: We were unable to account for the effect of a pedometer-based PA intervention for people with T2D through our examination of mediators. Our findings are inconsistent with some literature concerning PA interventions in diabetes; this may be due to variability in measures used or in study populations.     

A meta-analysis of children’s self-reports of dietary intake

Objective: Although research studies increasingly use children as primary reporters in dietary assessments, it is unclear how well children’s self-reported intake correlates with independently validated reports of their intake; this meta-analysis assesses that correlation.

Design: Moderators of the correlation between self-reported and independently validated intake were predicted a priori: type of dietary intake assessment (24 h recall, food diary and food frequency questionnaires), validation measures, parental assistance and age. Online databases were searched for articles published from 1990 to 2014 that compared children’s self-reports of dietary intake to validated observations of food intake in children age 4–16.

Main outcome measures: Summary effect size Pearson r between children’s self-reported dietary intake and independently validated dietary intake were calculated.

Results: In k = 32 samples from 23 studies, a statistically significant correlation (r = .48, Z = 7.26, p < .001) was found between children’s self-reported dietary intake and independently validated reports of dietary intake. Validation method (Q = 17.49, df = 2, p < .001) and parental assistance (Z = 2.03, p = .042) were significant moderators of this correlation. Self-report methodology (Q = 3.95, df = 2, p = .139) and age (Q = .02, p = .879) were not significant moderators of the distribution of effect sizes.

Conclusion: Together, these results provide baseline information about children’s recall in dietary intake assessments conducted with children as primary reporters.     

Acute Stress,Depression, and Anxiety Symptoms Among English and Spanish Speaking Children with Recent Trauma Exposure

A growing literature suggests the clinical importance of acute stress disorder symptoms in youth following potentially traumatic events. A multisite sample of English and Spanish speaking children and adolescents (N = 479) between the ages of 8–17, along with their caregivers completed interviews and self-report questionnaires between 2 days and 1 month following the event. The results indicate that children with greater total acute stress symptoms reported greater depressive (r = .41, p < .01) and anxiety symptoms (r = .53, p < .01). Examining specific acute stress subscales, reexperiencing was correlated with anxiety (r = .47, p < .01) and arousal was correlated with depression (r = .50, p < .01) and anxiety (r = .55, p < .01). Age was inversely associated with total acute stress symptoms (r = ?.24, p < .01), reexperiencing (r = ?.17, p < .01), avoidance (r = ?.27, p < .01), and arousal (r = ?.19, p < .01) and gender was related to total anxiety symptoms (Spearman’s ρ = .17, p < .01). The current study supports the importance of screening acute stress symptoms and other mental health outcomes following a potentially traumatic event in children and adolescents. Early screening may enable clinicians to identify and acutely intervene to support children’s psychological and physical recovery.     

Associations between psychological characteristics and indicators of metabolic syndrome among Chinese adults

Current knowledge about the relationship between psychological characteristics and metabolic syndrome (MetS) components is limited in Asian populations. The purpose of this study is to investigate linkages between physiological markers of MetS and life satisfaction, hostility, and depression in Chinese adults. Secondary analyses were conducted using cross-sectional data from parents of randomly selected middle school students participating in a pilot study in Qingdao, China. Among 440 parents who consented to participate (237 women, 203 men), 368 provided valid responses in all three categories of psychological characteristics, and only those subjects were included in these analyses. General linear models and logistic regressions were run separately by gender, controlling for covariates. Among women, life satisfaction was inversely associated with triglyceride levels (p = .04), LDL-C (p < .01), risk of hypertriglyceridemia (OR[.53], p < .01), HDL-C (OR[.78], p = .03), and MetS (OR[.52], p = .03). No associations were found between life satisfaction and any psychological characteristics among men. Among women, hostility was positively associated with triglyceride level (p = .04) and risk of hypertriglyceridemia (OR[2.12], p < .05). Among men, hostility was positively associated with waist circumference (p = .04), waist-hip ratio (p < .05), and fasting plasma insulin (p < .01). Depression was not associated with any physiological measurement in either gender. These findings indicate that relationships exist between certain psychological characteristics and physiological indicators of MetS among Chinese adults, although there may be important differences between genders.     

Trauma history as a resilience factor for patients recovering from total knee replacement surgery

Research concerning the impact of trauma history on individuals' ability to cope with subsequent events is mixed. While many studies find that trauma history increases vulnerability for conditions such as post-traumatic stress disorder and chronic pain, others reveal that there are benefits associated with moderate levels of stress (e.g. development of coping skills).

Objective: The present study investigated whether the experience of prior traumatic stressors would serve as a risk or resilience factor based on physical and emotional outcomes among patients recovering from total knee replacement surgery (TKR).

Design: 110 patients undergoing unilateral, TKR completed surveys before surgery, as well as one and three months following the procedure.

Results: Contrary to hypotheses, patients who reported more prior traumas experienced less severe pain and functional limitations at one- (β = ?.259, p = .006) and three-month follow-up assessments (β = ?.187, p = .04). A similar pattern emerged when specific types of traumas (e.g. interpersonal) were examined in relation to physical recovery. Further, patients’ trauma history was negatively related to symptoms of post-traumatic stress three-months following surgery (e.g. Avoidance: β = ?.200, p = .037).

Conclusion: Trauma history represents a source of resilience, rather than vulnerability, within the context of arthroplastic surgery.     

Does Symptom Type Moderate the Relationship Between Insight and Outcome in Cognitive Behavioral Therapy for Psychosis? A Preliminary Investigation

Insight has emerged as a potential predictor variable in cognitive behavioral therapy for psychosis (CBTp). However, previous research has produced mixed results. The present study aimed to clarify whether symptom type is a moderating variable. A group of psychotic patients (n = 44) were assessed through pre- and post-treatment in a CBTp specialty track in a partial hospital-based program in the USA. The Insight Scale was used to measure insight, and psychotic symptomatology was assessed using the Mini-International Neuropsychiatric Interview and the Behavior and Symptom Identification Scale. Patients showed a significant decrease in psychotic symptom scores over the course of treatment [t(43) = 3.59, p < .001, Cohen's d = .64]. Furthermore, illness awareness was specifically associated with a decrease in psychotic symptoms for patients who endorsed visual hallucinations (r = ? .68, p < .01), auditory hallucinations (r = ? .49, p = .01), and/or ideas of reference (r = ? .66, p < .01). Insight did not confer additional benefit for patients with paranoid delusions, mind reading, or thought insertion symptoms. These results are discussed in relation to treatment implications within the current US health care delivery system.     

Positive affectivity predicts successful and unsuccessful adaptation to stress

This study examined adaptation to work stress among public school teachers (n = 267). Regression analyses tested whether positive affect predicted successful and unsuccessful adaptation to stress (viz., resilience and burnout, respectively) after controlling for demographic characteristics and work stress. Positive affect was largely correlated with resilience (r = .65, p < .001) and burnout (r = ?.57, p < .001). The regression of resilience showed that positive affect had a direct effect (β = .66, p < .001) and the total model explained 44 % of the variance (R ² Change = 37 %). In the regression of burnout, positive affect also had a direct effect (β = ?.41, p < .001) and the total model explained 52 % of the variance (R ² Change = 14 %). Further analyses found no significant interaction between work stress and positive affect, but revealed that positive affect completely mediated the effect of work stress on resilience. Results provide support for the broaden-and-build theory of positive emotions, particularly the theory’s building and undoing effects.     

A computerized test for the assessment of mild cognitive impairment subtypes in sentence processing

This study examines thesentence processing ability of mild cognitive impairment (MCI) subtypes. In addition to standard MCI neuropsychological tests, an experimental approach was applied to assess language. 133 people (93 MCI/40 controls) participated in novel computerized sentence processing tasks. Results presented statistically significant differences between MCI/controls andMCI subtypes (ANOVA):(a) duration F(2,92) = 19.259,p < .001) in sentence construction; (b) correct answers (F(2, 89) = 8.560,p < .001) and duration (F2,89) = 15.525,p < .001)in text comprehension; (c) correct answers (F(2, 92) = 8.975,p < .001) andduration (F(2, 92) = 4.360,p = .016) in metaphoric sentences comprehension; (d) correct answers (F(2, 92) = 12.836,p < .001) andduration (F(2, 92) = 10.974,p < .001) in verb form generation. Subtle changes in MCIsubtypes could affect sentence processing and provide useful information for cognitive decline risk estimation and screening purposes.     

The buffering effect of family functioning on the psychological consequences of headache

The current study aimed to examine whether high family functioning mitigates the association between headache intensity and distress. The sample consisted of 124 patients with chronic or recurrent headache. Patients completed validated questionnaires about headache intensity, family functioning, and distress. Hierarchical regression analyses were performed to examine the interaction between headache intensity and family functioning on distress. Headache intensity was positively associated with distress (r = .28, p = .002). As hypothesized, family functioning moderated this association (B = ?.01, p = .023). More specifically, the positive association between headache intensity and distress was significant only among patients with lower family functioning (B = .01, p < .001) and not among patients with higher levels of family functioning (B = .006, p = .075). Functional families appear to buffer the distress level in patients; they showed relatively low levels of distress regardless of the severity of their headache. In contrast, patients with dysfunctional families who experienced more pain reported more distress, presumably because they did not receive adequate help and support from these families. This study underlines the importance of a broader perspective on family dynamics in coping with pain.
