How Harmonious and Obsessive Passion for Alcohol and Marijuana Relate to Consumption and Negative Consequences

OBJECTIVE

Although the concepts of harmonious and obsessive passion have been productive in explaining why people eagerly engage in such activities as sports, Internet use, and gambling, previous research has not yet extended these models to explain alcohol and marijuana use among college students. The current research was conducted to clarify the relationships among harmonious and obsessive passion, alcohol and marijuana use, and negative consequences.

METHOD

Two studies were conducted using online assessments. In Study 1, 748 heavy drinking college students (58% female) were recruited and completed measures of passion for drinking alcohol, alcohol use, and alcohol-related negative consequences. In Study 2, 352 regular marijuana-using students (54% female) were recruited and completed assessments of marijuana passion, marijuana use, and marijuana-related consequences.

RESULTS

Study 1 found that among heavy drinking college students, harmonious passion was a stronger predictor of increased consumption than was obsessive passion, whereas obsessive passion was a stronger predictor of alcohol-related problems than was harmonious passion. Study 2 revealed similar findings with regard to harmonious passion predicting marijuana consumption; however, unlike Study 1, no significant difference between the passions was found in predicting marijuana-related problems.

CONCLUSIONS

This research provides a novel perspective on motivation for alcohol and marijuana use. Findings suggest that understanding the locus of young adults' passion for substance use may be helpful in identifying those who are likely to develop a substance use disorder and therefore may be the most in need of assistance and intervention.

Treating Post-traumatic Stress Disorder in Patients with Multiple Sclerosis: A Randomized Controlled Trial Comparing the Efficacy of Eye Movement Desensitization and Reprocessing and Relaxation Therapy

OBJECTIVE

Multiple Sclerosis (MS) is a demyelinating autoimmune disease that imposes a significant emotional burden with heavy psychosocial consequences. Several studies have investigated the association between MS and mental disorders such as depression and anxiety, and recently researchers have focused also on Post-traumatic Stress Disorder (PTSD). This is the first study that investigates the usefulness of proposing a treatment for PTSD to patients with MS.

METHODS

A randomized controlled trial with patients with MS diagnosed with PTSD comparing Eye Movement Desensitization and Reprocessing (EMDR; n = 20) and Relaxation Therapy (RT; n = 22). The primary outcome measure was the proportion of participants that no longer meet PTSD diagnosis as measured with Clinician Administered PTSD Scale 6-months after the treatment.

RESULTS

The majority of patients were able to overcome their PTSD diagnosis after only 10 therapy sessions. EMDR treatment appears to be more effective than RT in reducing the proportion of patients with MS suffering from PTSD. Both treatments are effective in reducing PTSD severity, anxiety and depression symptoms, and to improve Quality of Life.

CONCLUSION

Although our results can only be considered preliminary, this study suggests that it is essential that PTSD symptoms are detected and that brief and cost-effective interventions to reduce PTSD and associated psychological symptoms are offered to patients, in order to help them to reduce the psychological burden associated with their neurological condition.

Assimilation, reflexivity, and therapist responsiveness in group psychotherapy for social phobia: A case study

OBJECTIVE

This case study examined reflexivity and the assimilation of problematic experiences, especially its progress within and between the Assimilation of Problematic Experiences Scale (APES) Stages 2-3, in group psychotherapy for social phobia.

METHOD

The data consisted of all of one client's turns expressing the two voices of her main problematic experience in 12 sessions, and all replies by the therapist in direct connection to them. The client's utterances were rated on the APES.

RESULTS

A detailed analysis of 13 conversational passages revealed that progress in assimilation happened only when the client took a reflexive stance towards her inner experience or outer actions. There were a few instances when she took a reflexive stance, but no progress in assimilation could be noted. A qualitative analysis of three conversational episodes showed how therapist responsiveness facilitated the client's increased reflexivity and progress in assimilation.

CONCLUSIONS

Reflexivity appears to be a necessary condition for progress in assimilation both at APES Stages 2 and 3, but the model should recognize that reflexivity can appear in diverse forms and at different levels. Therapist responsiveness and sensitivity to the client's assimilation process is crucial for a successful transition from Stage 2 to Stage 3.

Smoking Status and Substance Use Treatment Outcomes Among Spanish Speakers Enrolled in Substance Abuse Treatment

OBJECTIVE

Smoking is highly prevalent among individuals with drug and alcohol disorders. Concurrent tobacco dependence treatment during substance use disorder (SUD) treatment is supported, yet the association between SUD treatment outcomes and smoking status has been understudied in minorities, including Latinos.

METHOD

Participants were 322 Spanish-speaking Latinos enrolled in a SUD treatment study in 5 U.S. cities. Logistic regression examined associations between baseline smoking status and treatment outcomes for nontobacco substance use at follow-up. Covariates included age, gender, level of education, marital status, treatment group, and mandated treatment status.

RESULTS

Results indicated smokers had a reduced likelihood of abstinence for all nontobacco substances (p = .001) and their primary drug of use (p = .007).

CONCLUSIONS

Findings contribute to the growing literature indicating a possible beneficial effect of smoking cessation services on SUD treatment, specifically among Latinos. Further research is needed to identify ideal smoking cessation treatments for Latinos.

The Advantages of Parental Involvement in Cognitive-Behavioral Treatment of Childhood Obsessive-Compulsive Disorder: A Single-Case Example

BACKGROUND

Interventions for the treatment of anxiety disorders in children have a growing evidence base. Cognitive-behavioral therapy for the treatment of specific anxiety disorders in children and adolescents, including obsessive-compulsive disorder, is now an established intervention. However, a question remains concerning the benefits of parental involvement in treatment. Some studies report limited or no benefit of including parents in treatment, whereas other studies have indicated additional advantages of parental involvement.

INTERVENTION

The present case report describes the treatment of an 11-year-old girl with obsessive-compulsive disorder using cognitive-behavioral therapy derived largely from the treatment approaches outlined in Carr (2006), March and Mulle (1998), and Derisley, Heyman, Robinson, and Turner (2008). The child's mother attended all sessions and also a one-off parent-only session toward the end of treatment. The report considers the benefits of involving the child's mother in treatment and possible factors that could suggest parental involvement is indicated in future cases.

OUTCOMES

Both child and mother, and the therapist, believed that parental involvement had been an important and useful element of treatment. Possible reasons for benefits of parental involvement were considered to be high parental anxiety at the outset of treatment, age of the client, and involvement of the parent in obsessions and compulsions.

Relationship Functioning in Vietnam Veteran Couples: The Roles of PTSD and Anger

OBJECTIVE

Posttraumatic stress disorder (PTSD) and anger have been implicated separately in relationship dysfunction for veterans; however, no studies have simultaneously examined the roles of each of these constructs.

METHOD

This study examined the roles of PTSD and anger in the relationships of Vietnam veterans and their partners (n = 33 couples) with actor-partner interdependence modeling (APIM). Couples in which the veteran was diagnosed with PTSD (PTSD-positive; n = 20) were compared to couples in which the veteran did not have PTSD (PTSD-negative; n = 13) on measures of frequency of anger and relationship functioning.

RESULTS

PTSD-positive and PTSD-negative couples reported similar levels of relationship functioning, yet PTSD-positive veterans reported experiencing anger significantly more often than PTSD-negative veterans. Across groups, anger was predictive of relationship functioning, but PTSD severity was not.

CONCLUSIONS

Trait anger may have a more deleterious effect on relationship functioning than PTSD symptoms. Theoretical and clinical implications are discussed.

Aggression, Sibling Antagonism, and Theory of Mind During the First Year of Siblinghood: A Developmental Cascade Model

A developmental cascade model was tested to examine longitudinal associations among firstborn children's aggression, theory of mind (ToM), and antagonism toward their younger sibling during the 1st year of siblinghood. Aggression and ToM were assessed before the birth of a sibling and 4 and 12 months after the birth, and antagonism was examined at 4 and 12 months in a sample of 208 firstborn children (initial Mage  = 30 months, 56% girls) from primarily European American, middle-class families. Firstborns' aggression consistently predicted high sibling antagonism both directly and through poorer ToM. Results highlight the importance of examining longitudinal influences across behavioral, social-cognitive, and relational factors that are closely intertwined even from the early years of life.

Parent Use and Efficacy of a Self-Administered, Tablet-Based Parent Training Intervention: A Randomized Controlled Trial

Background

Parent training programs are traditionally delivered in face-to-face formats and require trained facilitators and weekly parent attendance. Implementing face-to-face sessions is challenging in busy primary care settings and many barriers exist for parents to attend these sessions. Tablet-based delivery of parent training offers an alternative to face-to-face delivery to make parent training programs easier to deliver in primary care settings and more convenient and accessible to parents. We adapted the group-based Chicago Parent Program (CPP) to be delivered as a self-administered, tablet-based program called the ezParentprogram.

Objective

The purpose of this study was to (1) assess the feasibility of the ezParentprogram by examining parent satisfaction with the program and the percent of modules completed, (2) test the efficacy of the ezParentprogram by examining the effects compared with a control condition for improving parenting and child behavior in a sample of low-income ethnic minority parents of young children recruited from a primary care setting, and (3) compare program completion and efficacy with prior studies of the group-based CPP.

Methods

The study used a two-group randomized controlled trial (RCT) design with repeated measures follow up. Subjects (n=79) were randomly assigned to an intervention or attention control condition. Data collection was at baseline and 12 and 24 weeks post baseline. Parents were recruited from a large, urban, primary care pediatric clinic. ezParentmodule completion was calculated as the percentage of the six modules completed by the intervention group parents. Attendance in the group-based CPP was calculated as the percentage of attendance at sessions 1 through 10. Satisfaction data were summarized using item frequencies. Parent and child data were analyzed using a repeated measures analysis of variance (RM-ANOVA) with simple contrasts to determine if there were significant intervention effects on the outcome measures. Effect sizes for between group comparisons were calculated for all outcome variables and compared with CPP group based archival data.

Results

ezParentmodule completion rate was 85.4% (34.2/40; 95% confidence interval [CI] = 78.4%-93.7%) and was significantly greater ( P<.05) than face-to-face CPP group attendance (135.2/267, 50.6%) attendance of sessions; 95% CI = 46.8%-55.6%). ezParentparticipants reported the program as very helpful (35/40, 88.0%) and they would highly recommend the program (33/40, 82.1%) to another parent. ezParentparticipants showed greater improvements in parenting warmth (F1,77 = 4.82, P<.05) from time 1 to 3. No other significant differences were found. Cohen’s d effect sizes for intervention group improvements in parenting warmth, use of corporal punishment, follow through, parenting stress, and intensity of child behavior problems were comparable or greater than those of the group-based CPP.

Conclusions

Data from this study indicate the feasibility and acceptability of the ezParentprogram in a low-income, ethnic minority population of parents and comparable effect sizes with face-to-face delivery for parents.

Identifying Psychosocial Variables That Predict Safer Sex Intentions in Adolescents and Young Adults

Young people are especially vulnerable to sexually transmitted infections (STIs). The triad of deliberate and effective safer sex behavior encompasses condom use, combined with additional information about a partner's sexual health, and the kind of sex acts usually performed. To identify psychosocial predictors of young people's intentions to have safer sex, as related to this triad, we conducted an online study with 211 sexually active participants aged between 18 and 24 years. Predictors [i.e., perceived behavioral control (PBC), subjective norms, and intention] taken from Fishbein and Ajzen's Reasoned Action Approach (RAA), were combined with more distal variables (e.g., behavioral inhibition, sensation seeking, parental monitoring, and knowledge about STIs). Beyond the highly predictive power of RAA variables, additional variance was explained by the number of instances of unprotected sexual intercourse (SI) during the last 12 months and reasons for using barrier protection during first SI. In particular, past condom non-use behavior moderated PBC related to intended condom use. Further, various distal variables showed significant univariate associations with intentions related to the three behaviors of interest. It may, therefore, be helpful to include measures of past behavior as well as certain additional distal variables in future safer sex programs designed to promote health-sustaining sexual behavior.

The experience of working with people that hoard: a Q-sort exploration

BACKGROUND

The impact and burden of working with people that hoard is largely unexplored.

AIM

To explore professionals' varied experiences of engagement and intervention with this client group.

METHOD

Five semi-structured interviews were initially conducted with professionals with detailed experience of working with people that hoard. A thematic analysis then identified key statements for a 49-item Q-set. The Q-sort was subsequently administered to public sector professionals with wide experience of working with people who hoard (N= 36; fire-fighters, environmental health, housing and mental health). Organizational support and job-related wellbeing measures (anxiety/contentment and depression/enthusiasm) were also administered.

RESULTS

Factor analysis identified three distinct clusters (a) therapeutic and client focused (N = 15), (b) shocked and frustrated (N = 2) and (c) pragmatic and task focused (N = 5). Therapeutic and client focused professionals were significantly more content and enthusiastic regarding their work with clients with hoarding difficulties.

CONCLUSIONS

Professionals experience and approach their work with people that hoard in discrete and dissimilar ways. Service delivery and training implications are considered.

Distress Tolerance and Social Support in Adolescence: Predicting Risk for Internalizing and Externalizing Symptoms Following a Natural Disaster

The purpose of the multi-measure, multi-wave, longitudinal study was to examine the interactive relation between behavioral distress tolerance (DT) and perceived social support (PSS) in 352 tornado-exposed adolescents aged 12-17 years (M=14.44; SD=1.74). At baseline, adolescents completed a computer-based task for DT, and self-report measures of PSS, depressed mood, posttraumatic stress disorder (PTSD), substance use, and interpersonal conflict. Symptoms also were assessed 4 and 12 months after baseline. Findings showed that lower levels of DT together with lower levels of PSS conferred risk for elevated symptoms of prospective depression (t(262)= -2.04, p=.04; r_{effect size}=0.13) and PTSD (t(195)= -2.08, p=.04; r_{effect size}=0.15) following a tornado. However, only PSS was significant in substance use t(139)=2.20, p=.03; r_{effect size}=0.18) and conflict (t(138)=-4.05, p<.0001; r_{effect size}=0.33) in our sample. Implications regarding adolescent DT, the transdiagnostic nature of PSS, and the clinical applications of our findings in the aftermath of a natural disaster are discussed.

Emotion, working memory, and cognitive control in patients with first-onset and previously untreated minor depressive disorders

Objective

To explore working memory and the ability to process different emotional stimuli in patients with first-onset and untreated minor (mild or moderate) depression.

Methods

Patients with first-onset and previously untreated minor depression, and healthy controls, were enrolled. Using a modified Sternberg working memory paradigm to investigate the combined effects of emotional stimuli with working memory, participants were exposed to experimental stimuli comprising pictures that represented positive, neutral and negative emotions. Working memory ability was measured using reaction time and accuracy, and emotion-processing ability was measured using pupil diameter.

Results

Out of 36 participants (18 patients with minor depression and 18 controls), there were no statistically significant between-group differences in response time and accuracy. Positive stimuli evoked changes in pupil diameter that were significantly smaller in patients with minor depression versus controls, but changes in pupil diameter evoked by negative stimuli were not significantly different between the two groups.

Conclusions

Healthy subjects showed a stronger emotional response to positive emotional stimuli than patients with first onset and previously untreated minor depression, but there were no differences in response to negative emotions. There were no statistically significant between-group differences in terms of speed of cognitive response, but this may have been due to the relatively small samples sizes assessed. Studies with larger sample populations are required to further investigate these results.

Self-narrative reconstruction in emotion-focused therapy: A preliminary task analysis

OBJECTIVE

This research explored the consolidation phase of emotion-focused therapy (EFT) for depression and studies-through a task-analysis method-how client-therapist dyads evolved from the exploration of the problem to self-narrative reconstruction.

METHOD

Innovative moments (IMs) were used to situate the process of self-narrative reconstruction within sessions, particularly through reconceptualization and performing change IMs. We contrasted the observation of these occurrences with a rational model of self-narrative reconstruction, previously built.

RESULTS

This study presents the rational model and the revised rational-empirical model of the self-narrative reconstruction task in three EFT dyads, suggesting nine steps necessary for task resolution: (1) Explicit recognition of differences in the present and steps in the path of change; (2) Development of a meta-perspective contrast between present self and past self; (3) Amplification of contrast in the self; (4) A positive appreciation of changes is conveyed; (5) Occurrence of feelings of empowerment, competence, and mastery; (6) Reference to difficulties still present; (7) Emphasis on the loss of centrality of the problem; (8) Perception of change as a gradual, developing process; and (9) Reference to projects, experiences of change, or elaboration of new plans.

CONCLUSIONS

Central aspects of therapist activity in facilitating the client's progression along these nine steps are also elaborated.

Evaluation of QuitNow Men: An Online, Men-Centered Smoking Cessation Intervention

BACKGROUND

Men continue to smoke cigarettes in greater numbers than women. There is growing evidence for the value of developing targeted, men-centered health promotion programs. However, few smoking cessation interventions have been designed for men. A gender-specific website, QuitNow Men, was developed based on focus group interview findings, stakeholder feedback, and evidence-based cessation strategies. The website was designed to incorporate a masculine look and feel through the use of images, direct language, and interactive content. Usability experts and end-users provided feedback on navigation and functionality of the website prior to pilot testing.

OBJECTIVES

The objectives of the pilot study were to describe (1) men's use and evaluations of the interactive resources and information on the QuitNow Men website, and (2) the potential of QuitNow Men to engage men in reducing and quitting smoking.

METHODS

A one-group, pretest-posttest study design was used. Men who were interested in quitting were recruited and invited to use the website over a 6-month period. Data were collected via online questionnaires at baseline, 3-month, and 6-month follow-up. A total of 117 men completed the baseline survey. Over half of those (67/117, 57.3%) completed both follow-up surveys.

RESULTS

At baseline, participants (N=117) had been smoking for an average of 24 years (SD 12.1) and smoked on average 15 cigarettes a day (SD 7.4). The majority had not previously used a quit smoking website (103/117, 88.0%) or websites focused on men's health (105/117, 89.7%). At the 6-month follow-up, the majority of men used the QuitNow Men website at least once (64/67, 96%). Among the 64 users, 29 (43%) reported using the website more than 6 times. The men using QuitNow Men agreed or strongly agreed that the website was easy to use (51/64, 80%), the design and images were appealing (42/64, 66%), they intended to continue to use the website (42/64, 66%), and that they would recommend QuitNow Men to others who wanted to quit (46/64, 72%). Participants reported using an average of 8.76 (SD 4.08) of the 15 resources available on the website. At 6-month follow-up, 16 of the 67 participants (24%) had quit, 27 (40%) had reduced their smoking and 24 (36%) had not changed their smoking habits. Repeated measures general linear model showed a significant decrease in the number of cigarettes smoked between the 3-month and 6-month follow-up (F1,63=6.41, P=.01, eta squared=0.09). Number of resources used on the website, quit confidence, nicotine dependence and age significantly predicted number of quit attempts by those still smoking at 6 months (F4,45=2.73, P=.04), with number of resources used being the strongest predictor (P=.02).

CONCLUSIONS

The results of this research support efforts to integrate gender-sensitive approaches in smoking cessation interventions and indicate that this novel Web-based resource has potential in supporting men's smoking cessation efforts.

The creation of the client reflexivity scale: A measure of minute fluctuations in self-awareness and exploration

OBJECTIVE

to design and pilot a reliable observer-based scale of client reflexivity that can be used on short segments of time ("coding intervals") across therapy sessions. Reflexivity was defined as the level of a client's awareness and exploration of his or her interiority. Interiority was defined as thoughts, feelings, sensations, intentions, and desires.

METHOD

The Client Reflexivity Scale (CRS) was designed through the coding of public access therapy videos featuring demonstrations of therapy. Along with the Experiencing Scale, the CRS was then piloted on one good outcome and one poor outcome session of cognitive-behavioural therapy for anxiety. Each session of therapy featured the same therapist but different clients. Two raters coded the sessions.

RESULTS

Weighted kappas for inter-rater reliability ranged from 0.74 to 0.81. The level of reflexivity was significantly higher in the good outcome session than the poor outcome session, though the trajectory of reflexivity for both sessions was the same. The CRS was also compared to the Experiencing Scale in order to determine similarities and differences between the scales.

CONCLUSIONS

the CRS reliably measured reflexivity within the therapy sessions, and in the future can be layered with other process measures in order to map interactions across therapy sessions.

Caregivers reflecting on the early days of childhood cancer

Much research examining primary caregivers of children with cancer has focused on their distress levels and coping strategies. Drawing on qualitative data from semi-structured interviews with 38 Australian primary caregivers, this article examines their experiences through their child's cancer diagnosis and early treatment period. However, it does so retrospectively with their child in remission (a minimum of 5 years post diagnosis). This methodology gave caregivers the time to evaluate and reflect on their experiences through their child's cancer. Interviews with caregivers were recorded, transcribed verbatim and analysed using a grounded constant comparison approach. The concept of neo-normal was developed to represent caregivers' responses to having a child with cancer - characterised by the existential threat of cancer, the shattering of notions of control and certainty in their capacity to protect their child's well-being and reliance on medical intervention. Paradoxically, conceding to this disempowered position facilitated new ways to be a caregiver of a child with cancer. The findings illustrate the social processes and cultural context in which caregivers construct new normalising strategies as they transition through their child's illness. The study also gives recognition to the vital care, advocacy and pseudo-nursing contributions that caregivers bring to the paediatric oncology setting.

Distinctive cardiac autonomic dysfunction following stress exposure in both sexes in an animal model of PTSD

It is unclear whether the poor autonomic flexibility or dysregulation observed in patients with posttraumatic stress disorder (PTSD) represents a pre-trauma vulnerability factor or results from exposure to trauma. We used an animal model of PTSD to assess the association between the behavioral response to predator scent stress (PSS) and the cardiac autonomic modulation in male and female rats. The rats were surgically implanted with radiotelemetry devices to measure their electrocardiograms and locomotor activity (LMA). Following baseline telemetric monitoring, the animals were exposed to PSS or sham-PSS. Continuous telemetric monitoring (24h/day sampling) was performed over the course of 7days. The electrocardiographic recordings were analyzed using the time- and frequency-domain indexes of heart rate variability (HRV). The behavioral response patterns were assessed using the elevated plus maze and acoustic startle response paradigms for the retrospective classification of individuals according to the PTSD-related cut-off behavioral criteria. During resting conditions, the male rats had significantly higher heart rates (HR) and lower HRV parameters than the female rats during both the active and inactive phases of the daily cycle. Immediately after PSS exposure, both the female and male rats demonstrated a robust increase in HR and a marked drop in HRV parameters, with a shift of sympathovagal balance towards sympathetic predominance. In both sexes, autonomic system habituation and recovery were selectively inhibited in the rats whose behavior was extremely disrupted after exposure to PSS. However, in the female rats, exposure to the PSS produced fewer EBR rats, with a more rapid recovery curve than that of the male rats. PSS did not induce changes to the circadian rhythm of the LMA. According to our results, PTSD can be conceptualized as a disorder that is related to failure-of-recovery mechanisms that impede the restitution of physiological homeostasis.

Relationships between Rodent White Adipose Fat Pads and Human White Adipose Fat Depots

The objective of this review was to compare and contrast the physiological and metabolic profiles of rodent white adipose fat pads with white adipose fat depots in humans. Human fat distribution and its metabolic consequences have received extensive attention, but much of what has been tested in translational research has relied heavily on rodents. Unfortunately, the validity of using rodent fat pads as a model of human adiposity has received less attention. There is a surprisingly lack of studies demonstrating an analogous relationship between rodent and human adiposity on obesity-related comorbidities. Therefore, we aimed to compare known similarities and disparities in terms of white adipose tissue (WAT) development and distribution, sexual dimorphism, weight loss, adipokine secretion, and aging. While the literature supports the notion that many similarities exist between rodents and humans, notable differences emerge related to fat deposition and function of WAT. Thus, further research is warranted to more carefully define the strengths and limitations of rodent WAT as a model for humans, with a particular emphasis on comparable fat depots, such as mesenteric fat.

Development and Examination of the Five-Factor Obsessive-Compulsive Inventory–Short Form

The Five-Factor Obsessive-Compulsive Inventory (FFOCI) is an assessment of obsessive-compulsive personality disorder (OCPD) that is based on the conceptual framework of the five-factor model (FFM) of personality. The FFOCI has 12 subscales that assess those five-factor model facets relevant to the description of OCPD. Research has suggested that the FFOCI scores relate robustly to existing measures of OCPD and relevant scales from general personality inventories. Nonetheless, the FFOCI’s length—120 items—may limit its clinical utility. This study derived a 48-item FFOCI–Short Form (FFOCI-SF) from the original measure using item response theory methods. The FFOCI-SF scales successfully recreated the nomological network of the original measure and improved discriminant validity relative to the long form. These results support the use of the FFOCI-SF as a briefer measure of the lower-order traits associated with OCPD.

Integrating Genetic, Neuropsychological and Neuroimaging Data to Model Early-Onset Obsessive Compulsive Disorder Severity

We propose an integrative approach that combines structural magnetic resonance imaging data (MRI), diffusion tensor imaging data (DTI), neuropsychological data, and genetic data to predict early-onset obsessive compulsive disorder (OCD) severity. From a cohort of 87 patients, 56 with complete information were used in the present analysis. First, we performed a multivariate genetic association analysis of OCD severity with 266 genetic polymorphisms. This association analysis was used to select and prioritize the SNPs that would be included in the model. Second, we split the sample into a training set (N = 38) and a validation set (N = 18). Third, entropy-based measures of information gain were used for feature selection with the training subset. Fourth, the selected features were fed into two supervised methods of class prediction based on machine learning, using the leave-one-out procedure with the training set. Finally, the resulting model was validated with the validation set. Nine variables were used for the creation of the OCD severity predictor, including six genetic polymorphisms and three variables from the neuropsychological data. The developed model classified child and adolescent patients with OCD by disease severity with an accuracy of 0.90 in the testing set and 0.70 in the validation sample. Above its clinical applicability, the combination of particular neuropsychological, neuroimaging, and genetic characteristics could enhance our understanding of the neurobiological basis of the disorder.

Both sides of the story: Exploring how improved and less-improved participants experience mindfulness-based stress reduction for social anxiety disorder

OBJECTIVE

What works for whom in mindfulness-based group interventions for social anxiety disorder (SAD)? The present article compared the experiences of 14 participants in a clinical study of mindfulness-based stress reduction (MBSR) for young adults with SAD.

METHODS

A two-staged mixed methods design was used to identify the participants who reported the highest (n = 7) and lowest (n = 7) levels of symptomatic change on outcome measures after treatment, and analyze qualitative in-depth interviews to explore what they experienced as helpful and unhelpful during the MBSR program. The qualitative interviews were analyzed using a thematic analysis methodology.

RESULTS

We identified the global theme of (i) Discovering agency to change or not feeling empowered through the MBSR program, and four sub-themes: (ii) Forming an active commitment or feeling ambivalence toward learning mindfulness, (iii) Engaging with others or avoiding contact with the group, (iv) Using the mindfulness exercises to approach or resigning when facing unpleasant experiences, and (v) Using the course to break interpersonal patterns or remaining stuck in everyday life.

CONCLUSIONS

MBSR may be helpful for young adults with SAD, although it may be important to match clients to their preferred form of treatment.

Association between burnout and depressive symptoms among Turkish dentists

Background/purpose

Health care professionals including dentists can experience increased professional burnout. The aim of the study was to evaluate the association between depressive symptoms and burnout among Turkish dentists.

Materials and methods

This study was conducted among a Turkish dentist sample in Ankara (Turkey) between February 2015 and August 2015. From a total of 500 dentists, 337 were included. A self-structured questionnaire, Maslach Burnout Inventory (MBI), and Beck Depression Inventory (BDI) were completed by the participants. The Student t test or analysis of variance was used to compare the variables.

Results

A total of 337 dentists (162 female dentists; mean age of participants 36 ± 4.45 years) participated in this study. Age, sex, professional status, years in profession, sector, and number of patients seen/d were factors affecting level of burnout (P < 0.05); 29% of the participants showed burnout and 22.2% showed depressive symptoms. Participants showed increase in emotional exhaustion (38%), increase in depersonalization (22%), and decrease in personal accomplishment (12%). The mean score of BDI significantly correlated with those of the MBI subscales (P < 0.05). All items of BDI except weight loss, irritability, and loss of appetite significantly correlated with MBI subscores (P < 0.05).

Conclusion

Dentists may face burnout and depressive symptoms during their professional life. Increased burnout level can give an idea on depressive symptoms, and may provide an opportunity to identify depression earlier. Creating and raising awareness about burnout are important to avoid and prevent depression among dentists. Further longitudinal studies analyzing the effects of interdisciplinary client-centered self-management programs for dentists on depressive symptoms and burnout must be planned.

Psychometric properties of the PTSD Checklist for DSM-5: a pilot study

BACKGROUND

To date there is a lack of studies assessing the psychometric properties of the recently revised PTSD Checklist (PCL), the PTSD Checklist for DSM-5 (PCL-5). The aim of this pilot study was to examine the psychometric properties of the PCL-5 in parents of children with burns.

METHODS

The participating parents (N=62, mean age=38) completed self-report questionnaires, 0.8-5.6 years after their child's burn. Measures were the PCL-5, the Impact of Event Scale-Revised (IES-R), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Perceived Stress Scale (PSS). Burn severity of the child and sociodemographic variables was obtained.

RESULTS

The parents' average PCL-5 scores were low to moderate. The internal consistency of the PCL-5 was satisfactory, with Cronbach's alpha ranging from 0.56 to 0.77 and mean inter-item correlations ranging from 0.22 to 0.73 for the four PCL-5 subscales and the PCL-5 total. The PCL-5 subscales were moderately to highly correlated with the corresponding IES-R subscales as well as MADRS and PSS (p<0.05), whereas associations with sociodemographics and burn severity were low to moderate.

CONCLUSIONS

This study provides preliminary support for the use of PCL-5. The results indicate satisfactory psychometric properties of the PCL-5 as measured with internal consistency, test-retest reliability, and aspects of convergent validity.

A rating measure of ADHD-related neuropsychological impairment in children and adolescents: Data from the Cognition and Motivation in Everyday Life (CAMEL) Scale from population and clinical samples

A new parent-completed questionnaire, the Cognition and Motivation in Everyday Life (CAMEL) scale, was developed to provide a comprehensive assessment of neuropsychological impairment in children related to attention-deficit/hyperactivity disorder (ADHD) across diverse cognitive, motivational and energetic domains. Its psychometric properties were investigated. A total of 60 items were generated to cover a wide range of putative ADHD-related neuropsychological processes. A clinical (n = 142) and community (n = 810) sample of parents with children between 6 and 16 years of age completed the questionnaire. Data on ADHD symptoms were also collected with a commonly-used, validated parent rating scale to explore the associations between CAMEL scores and dimensional measures of child ADHD and conduct problems. Factor analysis identified six factors which we labeled (i) Cognition, (ii) Self-Direction and Organization, (iii) Effort Engagement, (iv) Arousal Regulation, (v) Motivational Responsiveness, and (vi) Cautiousness. Self-Direction and Organization and Arousal Regulation were the strongest predictors for ADHD symptomatology. Self-Direction and Organization was strongly associated with inattention and Arousal Regulation with hyperactivity-impulsivity symptoms. Parents distinguished between broad neuropsychological domains in reliable and plausible ways, making distinctions between key aspects of functioning. However, the boundaries between these domains did not map directly onto the distinctions drawn within traditional models of ADHD deficits. Further research is required to examine the predictive validity and cost-effectiveness of the CAMEL scale compared to direct objective testing using laboratory measures in predicting prognosis and treatment outcome.

Burden of Care and Patient's Neuropsychiatric Symptoms Influence Carer's Evaluation of Cognitive Impairment

OBJECTIVES

The aim of this study was to explore what effects the carer's burden and patient's neuropsychiatric symptoms have on carer's report on patient's cognitive functioning and instrumental activities of daily living (IADL).

METHODS

We included 1,832 patients, 742 with mild cognitive impairment and 1,090 with dementia [mean age 75.2 years (SD 9.5), 56% women]. The following scales were used: Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Lawton and Brody IADL Scale, Neuropsychiatric Inventory Questionnaire (NPI-Q), Relatives' Stress Scale (RSS), Mini-Mental State Examination (MMSE), and Clock Drawing Test (CDT). Correlation analyses and multiple linear regression analyses were carried out to explore which factors were associated with IQCODE and IADL.

RESULTS

Spouses scored lower on the IQCODE compared with non-spouses in spite of equivalent MMSE and CDT scores. In a multiple linear regression analysis using IQCODE as a dependent variable, beta for MMSE was -0.368 (p < 0.001) adjusted for demographic factors. After adjusting also for RSS and NPI-Q, MMSE beta was -0.279 (p < 0.001), RSS beta 0.294 (p < 0.001), and NPI beta 0.237 (p < 0.001). Similar results were found using IADL as the dependent variable.

CONCLUSION

Carer's burden and neuropsychiatric symptoms of the patient are important biasing factors when carers report on cognitive function and IADL.

A WEB-BASED SURVEY OF MOTHER-INFANT BOND, ATTACHMENT EXPERIENCES, AND METACOGNITION IN POSTTRAUMATIC STRESS FOLLOWING CHILDBIRTH

OBJECTIVE

Postnatal depression is linked to adverse outcomes for parent and child, with metacognition and parenting experiences key variables in the development and maintenance of depression. The attachment between mother and infant is especially vulnerable to the effects of untreated postnatal depression. Despite high levels of reported postnatal stress symptoms, less attention has been given the relationship between attachment, metacognition, and postnatal traumatic symptoms in the context of birth trauma. This study tested several hypotheses regarding the relationships between recalled parenting experiences, metacognition, postnatal symptoms of posttraumatic stress disorder and depression and perceptions of the mother-infant bond, confirming and extending upon metacognitive and mentalization theories.

METHOD

A Web-based, cross-sectional, self-report questionnaire design was employed in an analog sample of new mothers. Participants were 502 women recruited via open-access Web sites associated with birth organizations. Structural equation modeling was employed for the principal analysis.

RESULTS

Metacognition fully mediated the relationship between recalled parenting experiences and postnatal psychological outcomes. Posttraumatic stress was indirectly associated with maternal perceptions of the bond, with this relationship mediated by depression.

CONCLUSION

Metacognition may have a key role in postnatal psychological distress. Where postnatal depression or traumatic birth experiences are identified, screening for posttraumatic stress is strongly indicated.

Time-based prospective memory difficulties in children with ADHD and the role of time perception and working memory

Time-based prospective memory (PM) is the ability to remember to perform an intended action at a given time in the future. It is a competence that is crucial for effective performance in everyday life and may be one of the main causes of problems for individuals who have difficulty in planning and organizing their life, such as children with attention deficit/hyperactivity disorder (ADHD). This study systematically examines different aspects of time-based PM performance in a task that involves taking an action at a given future time in a group of 23 children with ADHD who were compared with a matched group of typically-developing (TD) children. The children were asked to watch a cartoon and then answer a questionnaire about its content (ongoing task). They were also asked to press a key every 2 minutes while watching the cartoon (PM task). The relationships of time perception and verbal working memory with PM performance were examined by administering appropriate tasks. The results showed that the children with ADHD were less accurate than the TD children in the PM task and exhibited less strategic time-monitoring behavior. Time perception was found to predict PM accuracy, whereas working memory was mainly involved in time-monitoring behavior, but this applied more to the TD group than to the ADHD group, suggesting that children with ADHD are less able to use their cognitive resources when meeting a PM request.

Effects of parental emotional warmth on the relationship between regional gray matter volume and depression-related personality traits

The depression-related personality trait is associated with the severity of patients' current depressive symptoms and with the vulnerability to depression within the nonclinical groups. However, little is known about the anatomical structure associated with the depression-related personality traits within the nonclinical sample. Parenting behavior is associated with the depression symptoms; however, whether or not parenting behavior influence the neural basis of the depression-related personality traits is unclear. Thus in current study, first, we used voxel-based morphometry to identify the brain regions underlying individual differences in depression-related personality traits, as measured by the revised Neuroticism-Extraversion-Openness Personality Inventory, in a large sample of young healthy adults. Second, we use mediation analysis to investigate the relationship between parenting behavior and neural basis of depression-related personality traits. The results revealed that depression-related personality traits were positively correlated with gray matter volume mainly in medial frontal gyrus (MFG) that is implicated in the self-referential processing and emotional regulation. Furthermore, parental emotional warmth acted as a mediational mechanism underlying the association between the MFG volume and the depression-related personality trait. Together, our findings suggested that the family environment might play an important role in the acquisition and process of the depression-related personality traits.

College drinking problems and social anxiety: The importance of drinking context

Social anxiety more than quadruples the risk of developing an alcohol use disorder, yet it is inconsistently linked to heavy alcohol use. Elucidation of the relation between social anxiety and alcohol use is an important next step in treating and preventing risky drinking. College students routinely face potentially anxiety-provoking social situations (e.g., meeting new people) and socially anxious undergraduates are especially vulnerable to alcohol-related impairment. Drinking to cope with social anxiety is thought to reinforce alcohol use, yet research on coping-motivated drinking among socially anxious students has yielded inconsistent findings. Further, undergraduate drinking varies by drinking context, yet the role of context in drinking behaviors among socially anxious individuals remains unclear. The current study sought to examine the relationship of social anxiety and drinking quantity in specific drinking contexts among undergraduates (N = 611). We also evaluated whether relevant drinking contexts mediated the relationship between social anxiety and alcohol-related problems. Clinically elevated social anxiety was related to heavier consumption in negative emotion (e.g., feeling sad or angry) and personal/intimate (e.g., before sexual intercourse) contexts, but not social/convivial contexts (e.g., parties, bars). Quantity of alcohol consumed in negative emotion and personal/intimate contexts mediated the relationship between social anxiety and drinking problem severity. Drinking in personal/intimate contexts demonstrated a unique mediational role. Findings suggest that heavy drinking in particular contexts (especially personal/intimate and negative emotion) may play an important role in drinking problems among socially anxious individuals.

Consumer sleep tracking devices: a review of mechanisms, validity and utility

Consumer sleep tracking devices such as fitness trackers and smartphone apps have become increasingly popular. These devices claim to measure the sleep duration of their users and in some cases purport to measure sleep quality and awaken users from light sleep, potentially improving overall sleep. Most of these devices appear to utilize data generated from in-built accelerometers to determine sleep parameters but the exact mechanisms and algorithms are proprietary. The growing literature comparing these devices against polysomnography/actigraphy shows that they tend to underestimate sleep disruptions and overestimate total sleep times and sleep efficiency in normal subjects. In this review, we evaluate the current literature comparing the accuracy of consumer sleep tracking devices against more conventional methods used to measure sleep duration and quality. We discuss the current technology that these devices utilize as well as summarize the value of these devices in clinical evaluations and their potential limitations.

"When we are together I feel at home." Types and sources of social support among youth newly diagnosed with HIV in Kenya: implications for intervention

Social support helps youth manage psychosocial stress. Though many studies have investigated the role of social support in helping youth in developed countries cope with their HIV status, such research is lacking among youth living in sub-Saharan African countries, including Kenya. The importance of research on youth living with HIV in Kenya is enhanced given young people's unique developmental stages and the HIV prevalence rate of 8.8% among Kenyans aged 25 to 29 years. To gain further insight, qualitative focus group interviews were conducted with 53 youth aged 18 to 27 years who lived in the informal urban settlement of Kibera in Nairobi, Kenya. A phenomenological approach was used to analyse the data from which four major types of social support were identified: 1) emotional; 2) informational; 3) appraisal; and 4) instrumental. Within each of these overarching themes more specific sub-themes were identified. The youth also reported receiving social support from eight main sources: 1) family; 2) friends; 3) clinicians and clinical services; 4) counsellors; 5) support groups; 6) religious sources; 7) partners; and 8) other. These findings suggest that various forms of social support, provided by diverse sources, which may fall outside of those commonly involved in interventions, can help youth living with HIV cope with their diagnosis and promote healthy lifestyles. Future research should investigate the roles and interactions of different types and sources of support, specifically as they relate to interventions aiming to ameliorate the experiences of youth newly diagnosed with HIV.

Coping with occupational stress: the role of optimism and coping flexibility

The current study aimed at measuring whether coping flexibility is a reliable and valid construct in a UK sample and subsequently investigating the association between coping flexibility, optimism, and psychological health - measured by perceived stress and life satisfaction. A UK university undergraduate student sample (N=95) completed an online questionnaire. The study is among the first to examine the validity and reliability of the English version of a scale measuring coping flexibility in a Western population and is also the first to investigate the association between optimism and coping flexibility. The results revealed that the scale had good reliability overall; however, factor analysis revealed no support for the existing two-factor structure of the scale. Coping flexibility and optimism were found to be strongly correlated, and hierarchical regression analyses revealed that the interaction between them predicted a large proportion of the variance in both perceived stress and life satisfaction. In addition, structural equation modeling revealed that optimism completely mediated the relationship between coping flexibility and both perceived stress and life satisfaction. The findings add to the occupational stress literature to further our understanding of how optimism is important in psychological health. Furthermore, given that optimism is a personality trait, and consequently relatively stable, the study also provides preliminary support for the potential of targeting coping flexibility to improve psychological health in Western populations. These findings must be replicated, and further analyses of the English version of the Coping Flexibility Scale are needed.

Traumatic brain injury and co-occurring problems in prison populations: A systematic review

BACKGROUND

A growing body of epidemiological research suggests high rates of traumatic brain injury (TBI) in prisoners. The aim of this review is to systematically explore the literature surrounding the rates of TBI and their co-occurrences in a prison population.

METHODS

Six electronic databases were systematically searched for articles published between 1980-2014. Studies were screened for inclusion based on pre-determined criteria by two researchers who independently performed data extraction. Study quality was appraised based on a modified quality assessment tool.

RESULTS

Twenty-six studies were included in this review. Quality assessment ranged from 20% (poor) to 80% (good), with an overall average of 60%. Twenty-four papers included TBI prevalence rates, which ranged from 5.69-88%. Seventeen studies explored co-occurring factors including rates of aggression (n = 7), substance abuse (n = 9), anxiety and depression (n = 5), neurocognitive deficits (n = 4) and psychiatric conditions (n = 3).

CONCLUSIONS

The high degree of variation in TBI rates may be attributed to the inconsistent way in which TBI was measured, with only seven studies using valid and reliable screening tools. Additionally, gaps in the literature surrounding personality outcomes in prisoners with TBI, female prisoners with TBI and qualitative outcomes were found.

Prospective memory and intraindividual variability in ongoing task response times in an adult lifespan sample: the role of cue focality

To contribute to the ongoing conceptual debate of what traditional mean-level ongoing task (OT) costs tell us about the attentional processes underlying prospective memory (PM), we investigated costs to intraindividual variability (IIV) in OT response times as a potentially sensitive indicator of attentional processes. Particularly, we tested whether IIV in OT responses may reflect controlled employment of attentional processes versus lapses of controlled attention, whether these processes differ across adulthood, and whether it is moderated by cue focality. We assessed 150 individuals (19-82 years) in a focal and a nonfocal PM condition. In addition, external measures of inhibition and working memory were assessed. In line with the predictions of the lapses-of-attention/inefficient-executive-control account, our data support the view that costs to IIV in OT trials of PM tasks reflect fluctuations in the efficiency of executive functioning, which was related to failures in prospective remembering, particularly in nonfocal PM tasks, potentially due to their increased executive demands. The additional value of considering costs to IIV over and beyond traditional mean-level OT costs in PM research is discussed.

Measuring peer socialization for adolescent substance use: a comparison of perceived and actual friends' substance use effects

OBJECTIVE

There has been an increase in the use of social network analysis in studies of peer socialization effects on adolescent substance use. Some researchers argue that social network analyses provide more accurate measures of peer substance use, that the alternate strategy of assessing perceptions of friends' drug use is biased, and that perceptions of peer use and actual peer use represent different constructs. However, there has been little research directly comparing the two effects, and little is known about the extent to which the measures differ in the magnitude of their influence on adolescent substance use, as well as how these two effects may be redundant or separate constructs.

METHOD

Using Waves I and II of the National Longitudinal Study of Adolescent Health (Add Health) saturated subsample, we directly compared effects of perception of friends' use (PFU) and actual friends' use (AFU) on alcohol, cigarette, and marijuana initiation and persistence of use 1 year later. We also examined potential moderating effects of friendship quality and individual use on the relationship between perceived and actual friends' substance use and outcomes.

RESULTS

Results indicated that, overall, PFU effects were larger than AFU effects; however, these effects did not significantly differ in magnitude for most models. In addition, interaction effects differed for different substances and usage outcomes, indicating the meaning of PFU and AFU constructs (and thus, different types of peer socialization) may change based on substance and type of use.

CONCLUSIONS

These results highlight the multifaceted nature of peer influence on substance use and the importance of assessing multiple aspects of peer socialization while accounting for distinct contexts related to specific substances and use outcomes.
