We reexamined the psychometric properties of the Momentary Impulsivity Scale (MIS) in two young adult samples using daily diary (<i>N</i>=77) and ecological momentary assessment (<i>N</i>=147). A one-factor between- and within-person structure was supported, though "I felt impatient" loaded poorly within-person. MIS scores consistently related to emotion-driven trait impulsivity; however, MSSDs of MIS scores were unrelated to outcomes after accounting for aggregate MIS scores. We observed positi ...[more]

Project description:Despite enthusiasm for using intensive longitudinal designs to measure day-to-day manifestations of personality underlying differences between people, the validity of personality state scales has yet to be established. In this study, we evaluated the psychometrics of 20-item and 10-item daily, Big Five personality state scales in three independent samples (N = 1,041). We used multilevel models to separately examine the validity of the scales for assessing personality variation at the between- and within-person levels. Results showed that a five-factor structure at both levels fits the data well, the scales had good convergent and discriminative associations with external variables, and personality states captured similar nomological nets as established global, self-report personality inventories. Limitations of the scales were identified (e.g., low reliability, low correlations with external criterion) that point to a need for more, systematic psychometric work. Our findings provide initial support for the use of personality state scales in intensive longitudinal designs to study between-person traits, within-person processes, and their interrelationship.

Project description:IntroductionOne of the core symptoms of alcohol use disorder (AUD) is impulsivity. The recently published study on the Impulsivity Scale 12 (IS-12) offers a promising tool to use in clinics working with clients with AUD due to its simplicity. IS-12 includes subscales related tocognitive impulsivity and behavioral impulsivity, which are related to different aspects of AUD symptomatology. The aim of the study was to adapt IS-12 to polish and test its utility in a sample of patients diagnosed with AUD.MethodsUsing a Confirmatory Factor Analysis, we compared the two-factor model of the Polish adaptation of the BIS-11 and the IS-12 on a sample of 615 patients diagnosed with AUD. Additionally, we explored the association between the IS-12's cognitive impulsivity and behavioral impulsivity subscales and depressive symptoms, AUD severity, and suicidal ideation using Structural Equation Modeling on a subsample of 450 patients with AUD.ResultsThe IS-12 demonstrated a better model fit and good reliability compared to the BIS-11. Moreover, cognitive impulsivity predicted suicidal ideation, but not AUD severity, while behavioral impulsivity predicted AUD severity, but not suicidal ideation. Both subscales of IS-12 predicted depressive symptoms.ConclusionConsistent with prior work, findings indicate that the second-order factor model of the BIS-11 had reliability issues and evidenced poor model fit. In contrast, the IS-12 demonstrated a satisfactory model fit and was predictive of clinical symptomatology. Thus, utilizing an easy tool, such as IS-12, might be beneficial for researchers and clinicians working with patients with AUD.

Project description:Background:Considerable research has examined impulsivity between individuals, but less research has focused on whether impulsivity fluctuates within a person. Although previous research supports trait levels of impulsivity as a risk factor for increased alcohol involvement, it is unclear whether daily (i.e., state) fluctuations in impulsivity coincide with same-day drinking behaviors. The present pilot study tested (1) the extent to which impulsivity fluctuates within-person; (2) the influence of daily impulsivity on alcohol use outcomes across all days (i.e., whether drinking occurred, the number of drinks consumed, and intentions to drink) and on drinking days only (i.e., whether heavy episodic drinking occurred and the number of problems experienced); and (3) daily affect as moderators of these relationships. Method:Participants were 24 young adult drinkers without postsecondary education who completed a baseline plus 14 follow-up daily surveys. Each day, participants reported their impulsivity, affect, and drinking behavior. Results:Multilevel modeling revealed that 42.5% of the variability in daily impulsivity was due to within-person differences. Impulsivity was related to greater odds of heavy episodic drinking and more alcohol-related problems on drinking days. Positive affect moderated the relationship between impulsivity and alcohol-related problems, and the relationship between impulsivity and drinking intentions. Conclusions:Findings suggest that changes in positive affect and impulsivity may be a risk factor for alcohol problems in a daily context. Future research examining within-person impulsivity and negative outcomes may benefit from considering positive affect.

Project description:BackgroundEcological momentary assessment (EMA) uses mobile technology to enable in situ self-report data collection on behaviors and states. In a typical EMA study, participants are prompted several times a day to answer sets of multiple-choice questions. Although the repeated nature of EMA reduces recall bias, it may induce participation burden. There is a need to explore complementary approaches to collecting in situ self-report data that are less burdensome yet provide comprehensive information on an individual's behaviors and states. A new approach, microinteraction EMA (μEMA), restricts EMA items to single, cognitively simple questions answered on a smartwatch with single-tap assessments using a quick, glanceable microinteraction. However, the viability of using μEMA to capture behaviors and states in a large-scale longitudinal study has not yet been demonstrated.ObjectiveThis paper describes the μEMA protocol currently used in the Temporal Influences on Movement & Exercise (TIME) Study conducted with young adults, the interface of the μEMA app used to gather self-report responses on a smartwatch, qualitative feedback from participants after a pilot study of the μEMA app, changes made to the main TIME Study μEMA protocol and app based on the pilot feedback, and preliminary μEMA results from a subset of active participants in the TIME Study.MethodsThe TIME Study involves data collection on behaviors and states from 246 individuals; measurements include passive sensing from a smartwatch and smartphone and intensive smartphone-based hourly EMA, with 4-day EMA bursts every 2 weeks. Every day, participants also answer a nightly EMA survey. On non-EMA burst days, participants answer μEMA questions on the smartwatch, assessing momentary states such as physical activity, sedentary behavior, and affect. At the end of the study, participants describe their experience with EMA and μEMA in a semistructured interview. A pilot study was used to test and refine the μEMA protocol before the main study.ResultsChanges made to the μEMA study protocol based on pilot feedback included adjusting the single-question selection method and smartwatch vibrotactile prompting. We also added sensor-triggered questions for physical activity and sedentary behavior. As of June 2021, a total of 81 participants had completed at least 6 months of data collection in the main study. For 662,397 μEMA questions delivered, the compliance rate was 67.6% (SD 24.4%) and the completion rate was 79% (SD 22.2%).ConclusionsThe TIME Study provides opportunities to explore a novel approach for collecting temporally dense intensive longitudinal self-report data in a sustainable manner. Data suggest that μEMA may be valuable for understanding behaviors and states at the individual level, thus possibly supporting future longitudinal interventions that require within-day, temporally dense self-report data as people go about their lives.

Project description:Cannabis and alcohol are the most commonly used (il)licit drugs world-wide. We compared the effects of cannabis and alcohol use on within-person changes in impulsivity, hostility and positive affect at the momentary and daily levels, as they occurred in daily life.Observational study involving ecological momentary assessments collected via electronic diaries six random times a day for 28 consecutive days.Out-patients' everyday life contexts in Columbia, MO, USA.Ninety-three adult psychiatric out-patients (85% female; mean = 30.9 years old) with borderline personality or depressive disorders, who reported using only cannabis (n = 3), only alcohol (n = 58) or both (n = 32) at least once during the study period.Real-time, standard self-report measures of impulsivity, hostility and positive affect, as impacted by momentary reports of cannabis and alcohol use.Cannabis use was associated with elevated feelings of impulsivity at the day level [b = 0.83, 95% confidence interval (CI) = 0.17-1.49] and increased hostility at the momentary (b = 0.07, 95% CI = 0.01-0.12) and person (b = 0.81, 95% CI = 0.15-1.47) level. Alcohol use was associated with elevated feelings of impulsivity at the momentary (b = 0.42, 95% CI = 0.13-0.71) and day levels (b = 0.82, 95% CI = 0.22-1.41) and increased positive affect at the momentary (b = 0.12, 95% CI = 0.06-0.18) and day (b = 0.33, 95% CI = 0.16-0.49) levels.Cannabis and alcohol use are associated with increases in impulsivity (both), hostility (cannabis) and positive affect (alcohol) in daily life, and these effects are part of separate processes that operate on different time-scales (i.e. momentary versus daily).

Project description:BackgroundThe Penn Alcohol Craving Scale (PACS) is an instrument with good psychometric properties that is widely used to assess alcohol craving. Based on the assumption that the experience of craving is independent of substance type, the Polish version of the PACS was modified to measure drug craving, thus creating the Penn Drug Craving Scale (PDCS). The analyses presented in the paper aim to verify the hypothesis that the PDCS has a unidimensional structure, is highly reliable and features longitudinal measurement invariance.MethodsThe research was conducted in 14 inpatient and 13 outpatient randomly selected facilities that provide psychosocial therapy to people with substance use disorder (SUD) in Poland, during June 2018 -July 2019. The data used for the analyses came from 282 patients diagnosed on the basis of ICD-10 criteria (F11.2-F19.2). The paper presents analyses with the application of: [1] confirmatory factor analysis (CFA) conducted on the basis of a polychoric correlation matrix and the WLSMV estimator; [2] a reliability estimate using Cronbach's alpha and coefficient omega; [3] verification of longitudinal measurement invariance between the beginning and end of therapy; [4] evaluation of criterion validity; [5] normalisation of the raw scores.ResultsThe CFA results confirmed a unidimensional PDCS structure (RMSEA = 0.047, 95% CI: 0.000-0.103; CFI = 0.999; TLI = 0.999) and a high reliability of the scale (ω = 0.93). Moreover, a strict longitudinal measurement invariance of the instrument was confirmed.ConclusionsAccurate assessment of craving is possible only with valid and reliable instruments. Therefore, the psychometric properties of the PDCS were verified based on the latest statistical approaches. The scale is a valid and highly reliable tool featuring longitudinal measurement invariance and can be usefully used for research and clinical purposes. Thus, the Polish version of the PACS has been modified and successfully applied to the population of people with SUD.

Project description:BackgroundTheoretical models of alcohol use posit that individuals consume alcohol to ameliorate negative affect or to heighten positive affect. It is important, however, to consider the influence of factors that may determine an individual's tendency to consume excessive amounts of alcohol under positive and negative circumstances. Thus, the current study examined a large sample of young adults to clarify whether positive and negative affect predict total alcohol consumption on drinking days and whether facets of impulsivity moderate these relationships.MethodsSix-hundred ninety-three young adults (Mage = 19.71 years, SD = 2.04; female = 62.9%) completed the Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scales at baseline followed by daily measures of positive and negative affect and self-reported alcohol use for 13 days. Generalized linear mixed models were specified to assess the role of pre-consumption affect on total drinks consumed across drinking days and to determine the moderating effect of each BIS/BAS subscale.ResultsParticipants were significantly more likely to drink in greater quantities on occasions preceded by higher positive affect but not negative affect. While fun-seeking positively predicted total drinks consumed, there were no significant interaction effects between the BIS/BAS subscales and affect on total drinks consumed.ConclusionsThese findings challenge existing affect regulation models and have implications for ecological momentary interventions aimed at addressing hazardous drinking behaviors.

Project description:BackgroundNegative affect and difficulties in its regulation have been connected to several adverse psychological consequences. While several questionnaires exist, it would be important to have a theory-based measure that includes clinically relevant items and shows good psychometric properties in healthy and patient samples. This study aims at developing such a questionnaire, combining the two Gross [1] scales Reappraisal and Suppression with an additional response-focused scale called Externalizing Behavioral Strategies covering clinically relevant items.MethodsThe samples consisted of 684 students (mean age = 23.3, SD = 3.5; 53.6% female) and 369 persons with mixed mental disorders (mean age = 36.0 SD = 14.6; 71.2% female). Items for the questionnaire were derived from existing questionnaires and additional items were formulated based on suggestions by clinical experts. All items start with "When I don't feel well, in order to feel better…". Participants rated how frequently they used each strategy on a 5-point Likert scale. Confirmatory Factor Analyses were conducted to verify the factor structure in two separate student samples and a clinical sample. Group comparisons and correlations with other questionnaires were calculated to ensure validity.ResultsAfter modification, the CFA showed good model fit in all three samples. Reliability scores (Cronbach's α) for the three NARQ scales ranged between .71 and .80. Comparisons between students and persons with mental disorders showed the postulated relationships, as did comparisons between male and female students and persons with or without Borderline Personality Disorder. Correlations with other questionnaires suggest the NARQ's construct validity.ConclusionsThe results indicate that the NARQ is a psychometrically sound and reliable measure with practical use for therapy planning and tracking of treatment outcome across time. We advocate the integration of the new response-focused strategy in the Gross's model of emotion regulation.

Project description:Strengths use is an essential personal resource to consider when designing higher-educational programs and interventions. Strengths use is associated with positive outcomes for both the student (e.g., study engagement) and the university (e.g., academic throughput/performance). The Strengths Use Scale (SUS) has become a popular psychometric instrument to measure strengths use in educational settings, yet its use has been subjected to limited psychometric scrutiny outside of the U.S. Further, its longitudinal stability has not yet been established. Given the wide use of this instrument, the goals of this study were to investigate (a) longitudinal factorial validity and the internal consistency of the scale, (b) its equivalence over time, and (c) criterion validity through its relationship with study engagement over time. Data were gathered at two-time points, 3 months apart, from a sample of students in the Netherlands (n = 360). Longitudinal confirmatory factor analyses showed support for a two-factor model for overall strengths use, comprised of Affinity for Strengths and Strengths Use Behaviors. The SUS demonstrated high levels of internal consistency at both the lower- and upper bound limits at both time points. Further, strict longitudinal measurement invariance was established, which confirmed the instrument's temporal stability. Finally, criterion validity was established through relating strengths use to study engagement at different time stamps. These findings support the use of the SUS in practice to measure strengths use and to track the effectiveness of strengths use interventions within the higher education sector.

Project description:BackgroundEcological momentary assessment (EMA) is a method for capturing the changes in the variables in daily life with increased accuracy and decreased recall bias. The PsyMate scale assesses momentary moods in daily life and can be used in various settings.ObjectiveThe aim of this study was to develop a Korean version of the PsyMate (K-PsyMate) scale and evaluate its psychometric properties by using the EMA method in patients with moyamoya disease (MMD) in South Korea.MethodsPatients with MMD aged over 18 years were recruited from July 2018 to January 2019 at the inpatient and outpatient departments of a university hospital in South Korea. The K-PsyMate scale comprising 13 items was developed following a translation/back translation approach of the English version and loaded onto a mobile app. Participants were instructed to enter their moods 4 times a day for 7 consecutive days. Content validity index, factor analysis, and Pearson's correlation were performed for validity analysis. For reliability, intraclass correlation coefficients between the first and last measurements were estimated by mean rating, absolute agreement, and a 2-way mixed-effects model. Usability was analyzed through a descriptive analysis, 2-tailed t test, and analysis of variance, and the results were confirmed by Mann-Whitney U test and the Kruskal-Wallis test, as the dependent variable was not normally distributed.ResultsIn total, 1929 assessments from 93 patients were analyzed. The mean age of the participants was 40.59 (SD 10.06) years, and 66 (71%) of the 93 participants were women. Content validity was excellent as content validity index was 0.99, and 2 factors, negative affect and positive affect, were derived by an exploratory factor analysis. The correlations between the subdomains of the K-PsyMate scale and Hospital Anxiety and Depression Scale were significant (P<.001). The agreement between the first and last measurements was poor to moderate according to the obtained intraclass correlation coefficient values. Usability was evaluated by 67 (72%) out of the 93 participants. The participants rated the accuracy of assessing their momentary moods on the app at 4.13 (SD 0.97), easiness in understanding questions, operating, and inputting answers at 4.12 (SD 0.88), and interruption by the survey alarms at 2.48 (SD 1.02) out of 5.ConclusionsThe K-PsyMate scale has good validity but poor to moderate agreement, which reflects the characteristics of the EMA data collected in real and natural living environments without control. The findings of our study show that the K-PsyMate scale uploaded in a mobile app can be a valid and reliable tool for evaluating the momentary mood of patients with MMD because using a mobile app is convenient and patients are familiar with their own smartphones, which they use in their daily lives.
