Currently, little is known about the association between assessment intensity, burden, data quantity, and quality in experience sampling method (ESM) studies. Researchers therefore have insufficient information to make informed decisions design of their ESM study. Our aim was investigate effects different frequencies questionnaire lengths on compliance, careless responding. Students ( n = 163) received either a 30- or 60-item three, six, nine times per day for 14 days. Preregistered...
In recent years, the popularity of procedures for collecting intensive longitudinal data, such as experience-sampling method, has increased greatly. The data collected using designs allow researchers to study dynamics psychological functioning and how these differ across individuals. To this end, are often modeled with multilevel regression models. An important question that arises when design studies is determine number participants needed test specific hypotheses regarding parameters...
A growing interest in understanding complex and dynamic psychological processes as they occur everyday life has led to an increase studies using ambulatory assessment techniques, including the experience-sampling method (ESM) ecological momentary assessment. These methods, however, tend involve numerous forking paths researcher degrees of freedom, even beyond those typically encountered with other research methodologies. Although a number researchers working ESM techniques are actively...
COVID-19 lockdown measures have profoundly impacted adolescent' daily life, with research suggesting an increase in irritability, stress, loneliness, and family conflict. A potential protective factor is parent-child relationship quality; however, no studies investigated this. We used data from SIGMA, a longitudinal, experience sampling cohort study, which N = 173 adolescents aged 11 to 20 were tested before during COVID-19. Multilevel analyses showed decreased daily-life irritability...

ACT in Daily Life (ACT-DL) is a blended-care Ecological Momentary Intervention that extends into the daily life of individuals, improving psychotic distress, negative symptoms, and global functioning. However, it remains unclear whether ACT-DL works equally for everyone. We investigated moderators (i.e., sociodemographic information, personality, trauma history) determine clinical outcomes individuals with early psychosis receiving ACT-DL. Seventy-one participants from INTERACT trial, using...
Since the introduction of experience sampling method (ESM), there have been concerns that repeated assessments typically related to this may alter behavior, thoughts, or feelings participants. Previous studies offered mixed results with some reporting reactive changes, while others failed find such effects. Our aim was investigate under which circumstances ESM induces Students (N = 151) were randomly assigned receive a questionnaire containing 30 60 items three, six, nine times per day for...
<b><i>Introduction/Objective:</i></b> This study aimed to investigate efficacy of Acceptance and Commitment Therapy in Daily Life (ACT-DL), combining face-to-face therapy with an Ecological Momentary Intervention (EMI), addition treatment as usual (TAU) for psychotic distress, comparison TAU. <i>Methods</i>: Individuals aged 15–65 years clinically established ultra-high risk or first episode psychosis were randomly assigned TAU ACT-DL+TAU. ACT-DL+TAU...
Can we experience positive (PA) and negative affect (NA) separately (i.e., affective independence), or do these emotional states represent the mutually exclusive ends of a single bipolar continuum bipolarity)?Building on previous emotion theories, propose that relation between PA NA is not invariable, but rather fluctuates in response to changing situational demands.Specifically, argue our system shifts from relative independence stronger bipolarity when encounter events situations activate...
Affect dynamics are often studied by means of first-order autoregressive (AR) modeling applied to intensive longitudinal data. A key target in these studies is the AR parameter, which tied conceptually regulatory behavior affective process. The data typically gathered using experience sampling methods, designed pick up on fluctuations variables as they evolve over time naturalistic settings. In this manuscript, we compare classical time-contingent designs episode-contingent designs, initiate...
In response to the replication and confidence crisis across various empirical disciplines, ensuring validity of research has gained attention. High is crucial for obtaining replicable robust study outcomes when both exploring new questions replicating previous findings. this study, we aimed address issue by developing a comprehensive checklist assist researchers in enhancing monitoring their research. After systematically analyzing findings on validity, list potential items was compiled....
The experience sampling method (ESM) has become a popular tool across various fields ofpsychology. However, the intensive nature of ESM raises concerns about carelessresponding, where participants respond to questionnaires without paying sufficientattention them. To better understand careless responding in context ESM, thisstudy investigated its temporal dynamics three commonly used sample types(community, student, clinical). We leveraged four indicators fromprevious research — response...

The network theory of psychopathology inspired clinicians and researchers to use idiographic networks study how symptoms an individual interact over time, hoping find the target symptom(s) for intervention most effectively break this self-sustaining network. These are often based on vector autoregressive (VAR) model rely intensive longitudinal data collected in patients’ daily lives. Nowadays, one major challenge these faced with is that they used without sufficient quality assessments....
The Experience Sampling Method (ESM) plays a pivotal role in investigating the dynamics of psychopathological processes daily life. A crucial question when designing ESM studies concerns sample size needed, defined by number participants (𝑁) and measurement occasions per participant (𝑇). Higher 𝑁 𝑇 increase power, but also researcher burden, study cost. Current approaches for planning rarely account these feasibility financial constraints explicitly, despite significant variations studies’...

Purpose: Self-harm is a leading cause of death and injury worldwide especially common amongst adolescents. Adverse childhood experiences (ACEs) are characterized as risk factor for self-harm within the Integrated-Motivational Volitional (IMV) model. However, it unclear how ACEs relate to unfolds in daily-life, research investigating potential protective factors association between scarce. Here, we investigated whether were associated with lifetime daily-life using Experience Sampling...
Abstract Background and Hypothesis Childhood adversity is associated with a myriad of psychiatric symptoms, including psychotic experiences (PEs), multiple psychological processes that may all mediate these associations. Study Design Using network approach, the present study examined complex interactions between childhood adversity, PEs, other mediators (ie, activity-related social stress, negative affect, loneliness, threat anticipation, maladaptive cognitive emotion regulation, attachment...
Abstract Background Psychotic experiences (PEs) and social isolation (SI) seem related during early stages of psychosis, but the temporal dynamics between two are not clear. Literature so far suggests a self-perpetuating cycle wherein momentary increases in PEs lead to withdrawal, which, subsequently, triggers at next point time, especially when SI is associated with increased distress. The current study investigated daily-life associations PEs, as well role SI-related general affective...
