Examining time-varying dynamics of co-occurring depressed mood and anxiety.

Background: Dimensional frameworks of psychopathology call for multivariate approaches to map co-occurring disorders to index what symptoms emerge when and for whom. Ecological momentary assessment (EMA) offers a method for assessing and differentiating the dynamics of co-occurring symptoms with greater temporal granularity and naturalistic context. The present study used multivariate mixed effects location-scale modeling to characterize the time-varying dynamics of depressed mood and anxiety for women diagnosed with social anxiety disorder (SAD) and major depression (MDD).

Characterizing the momentary association between loneliness, depression, and social interactions: Insights from an ecological momentary assessment study.

Evidence suggests that loneliness causes people to feel more depressed. It is unknown, however, why this association occurs and whether momentary versus chronic experiences of loneliness are implicated. Theoretical accounts suggest that momentary feelings of loneliness produce two competing motivations: social reaffiliation and social withdrawal.

Avoidance and fear day by day in social anxiety disorder.

Objective: Theories assert that avoidance maintains maladaptive anxiety over time, yet a clear prospective test of this effect in the day-by-day lives of people with social anxiety disorder (SAD) is lacking.

Method: We used intensive longitudinal data to test prospective relationships between social fear and social avoidance in 32 participants with SAD who reported on a total of 4256 time points.

Results: Results suggested that avoidance strongly predicted future anxiety, but only in a minority of people with SAD.

Whose Approval Matters Most? Examining Discrepancies in Self- and Other- Perceptions of Drinking.

Background: Research demonstrates that perceptions of others' attitudes toward drinking behaviors () are strong predictors of alcohol consumption and problems. Personalized normative feedback (PNF) aims to reduce the discrepancy between one's perception of others' attitudes toward drinking and others' attitudes toward drinking. An implicit assumption of PNF is that self and (perceived) other attitudes toward drinking are aligned (thus, shifting one's perceptions of others' attitudes shifts one's own attitudes).

Commentary on Stull et al.: Considering person-specific heterogeneity when modeling time-varying trends.

TVEM represents an important statistical method for modeling non-linear, dynamic processes. However, TVEM models the -level process for the focal effect. As addiction- and recovery-related processes demonstrate person-specific heterogeneity, we encourage researchers to model non-parametric non-ergodic change to advance our understanding of how, when, and for whom change occurs.

Investigating Individual Variation Using Dynamic Structural Equation Modeling: A Tutorial with Tinnitus.

A growing body of research suggests that standard group-based models might provide little insight regarding individuals. In the current study, we sought to compare group-based and individual predictors of bothersome tinnitus, illustrating how researchers can use dynamic structural equation modeling (DSEM) for intensive longitudinal data to examine whether findings from analyses of the group apply to individuals. A total of 43 subjects with bothersome tinnitus responded to up to 200 surveys each.

Daily-level relationships between negative affect, negative emotion differentiation, and cannabis behaviors among a high-risk sample of young adults.

Prior research suggests that higher trait negative emotion differentiation (NED; one's ability to make subtle distinctions between different negative emotional states) is associated with consuming less alcohol when experiencing high negative affect (NA) in daily life. Yet, whether these findings extend to cannabis use behaviors is unclear. The present study used intensive daily data to test whether NED moderated the relationship between NA and cannabis behaviors.

Examining Associations Between Negative Affect and Substance Use in Treatment-Seeking Samples: A Review of Studies Using Intensive Longitudinal Methods.

Purpose Of Review: Understanding dynamic relationships between negative affect and substance use disorder (SUD) outcomes, including craving, may help inform adaptive and personalized interventions. Recent studies using intensive longitudinal methods were reviewed to examine relationships between negative affect and the outcomes of either craving or substance use during and following SUD treatment.

Recent Findings: Results on associations between negative affect and craving/substance use were mixed and difficult to synthesize, given methodological differences across studies.

Using the experience sampling method to support clinical practice: An illustration with problematic cannabis use.

The experience sampling method (ESM) has been frequently used in clinical research; however, there is low translational uptake in clinical practice. This may be due to challenges with interpreting individual-level data at granular intervals. We provide an illustrative example of how ESM can be leveraged to generate personalized cognitive-behavioral strategies for problematic cannabis use.

Personalized networks of social anxiety disorder and depression and implications for treatment.

Introduction: Social anxiety disorder (SAD) and major depressive disorder (MDD) often co-occur; however, there is limited research evaluating how cognitive-affective and behavioral factors maintain SAD and MDD for specific individuals. Evidence suggests that individuals exhibit symptom-level heterogeneity, necessitating a person-specific approach to assessment and intervention. We compared group and person-specific models of SAD-MDD comorbidity and hypothesized that individuals would demonstrate person-specific patterns of comorbidity factors that differed from the group.

Interpersonal problems in social anxiety disorder across different relational contexts.

People with social anxiety disorder (SAD) frequently report interpersonal problems across various domains; however, it is unclear whether these problems are observable by others or represent negatively biased self-report. We assessed the interpersonal problems of people with and without SAD using self-report, friend, and romantic partner report. We hypothesized that SAD diagnosis would predict self-reported problems across multiple interpersonal domains, but restricted domains of informant report.

Feasibility and utility of idiographic models in the clinic: A pilot study.

Idiographic, or individual-level, methodology has been touted for its potential clinical utility. Empirically modeling relationships between symptoms for a single individual may offer both the client and therapist information that is useful for case conceptualization and treatment planning. However, few studies have investigated the feasibility and utility of integrating idiographic models in a clinical setting.

[Not Available].

Theorists and clinicians have long noted the need for idiographic (i.e., individual-level) designs within clinical psychology.

Feasibility of Intensive Ecological Sampling of Tinnitus in Intervention Research.

Objective: To assess whether adults with bothersome tinnitus will complete multiple ecological momentary assessments (EMAs) per day, including those during a therapeutic intervention trial. EMA is defined as repeated sampling of subjects' current behaviors and experiences in real time.

Study Design: Twelve-week longitudinal cohort study conducted from August 28, 2017, to December 14, 2017.
