This three-wave study examined associations between a motivational construct future time perspective (FTP) and teachers’ identity (TI) in a sample of Dutch student teachers (N = 368). Additionally, gender and educational level were included as factors affecting FTP and TI. Random intercept cross-lagged panel models indicated that FTP and TI were moderately and positively correlated at the between-person level. At the within-person level, positive cross-lagged effects from wave 2 FTP on wave 3 TI were uncovered. Male student teachers and those that are academically educated reported weaker FTP and TI relations compared to their counterparts. Implications for practice are discussed.

BackgroundLittle is known about the association between fear of movement (kinesiophobia) and objectively measured physical activity (PA), the first 12 weeks after cardiac hospitalization.PurposeTo assess the longitudinal association between kinesiophobia and objectively measured PA and to assess the factor structure of kinesiophobia.MethodsWe performed a longitudinal observational study. PA was continuously measured from hospital discharge to 12 weeks using the Personal Activity Monitor. The PAM measures time spent per day in PA-intensity categories: light, moderate and heavy. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK) at four time points (hospital discharge, 3, 6 and 12 weeks). The longitudinal association between PA-intensity and kinesiophobia was studied with a random intercept cross lagged panel model (RI-CLPM). A RI-CLPM estimates effects from kinesiophobia on objectively measured PA and vice versa (cross-over effects), and autoregressive effects (e.g. kinesiophobia from one occasion to the next).ResultsIn total, 116 patients (83.6% male) with a median age of 65.5 were included in this study. On no occasion did we find an effect of kinesiophobia on PA and vice versa. Model fit for the original model was poor (X2: = 44.646 P<0.001). Best model fit was found for a model were kinesiophobia was modelled as a stable between factor (latent variable) and PA as autoregressive component (dynamic process) (X2 = 27.541 P<0.12).ConclusionKinesiophobia and objectively measured PA are not associated in the first 12 weeks after hospital discharge. This study shows that kinesiophobia remained relatively stable, 12 weeks after hospital discharge, despite fluctuations in light to moderate PA-intensity.

Tourism experiences, also called vacations, are known to boost subjective well-being, although it has been argued that the effects are primarily affective in nature and short-lived. We argue that this is a methodological artifact due to the brief duration—1 year or less—of almost all extant longitudinal studies of tourism experience effects. Based on broaden-and-build and personal resource theories, we hypothesize that tourism experiences contribute to both affective and cognitive components of subjective well-being over a multi-year timespan. Using random intercept cross-lagged panel models, we tested these hypotheses in 8 years of panel data based on a representative sample of the population of the Netherlands. We found both between- and within-individual effects of vacation frequency on cognitive as well as affective well-being. More frequent vacationers experienced higher life satisfaction and lower negative affect, while the average participant also experienced slightly higher life satisfaction and positive affect following a year with higher vacation frequency. Increases in life satisfaction also predicted more frequent vacationing in a following year, consistent with an “upward spiral” pattern of improving well-being based on accumulation of positive experiences, as suggested by the broaden-and-build theory.

This longitudinal study investigated reciprocal associations among various professional identity tensions and Dutch primary student teachers’ teacher identity. Students (N = 201, 82.9% female) completed the professional identity tensions scale and the teacher identity measurement scale across three waves. Random intercept cross-lagged panel models showed that five out of nine investigated professional identity tensions were negatively associated with teacher identity at the inter-individual level. At the intra-individual level, no significant cross-lagged relationships were detected. Our findings imply that the development of professional identity tensions and teacher identity are not automatically interrelated and should, therefore, be both explicitly addressed in teacher education.

This three-wave study examined relationships between preservice teachers’ diversity-related stress, teaching self-efficacy (TSE), and intentions to leave the profession. Participants (N = 386) from four Dutch teacher training programs completed surveys on diversity-related stress, intentions to leave, and TSE over 18 months. Random intercept cross-lagged panel models showed that higher diversity-related stress predicted lower TSE and increased intentions to leave. Within-person analyses revealed a complex reciprocal relationship: Highly self-efficacious teachers reported more stress and vice versa. Finally, intentions to leave led to lower TSE at Timepoint 3 only. Findings align with social-cognitive theory, highlighting the interplay between stress, TSE, and career intentions.

The main objective of the study is to determine if non-specific physical symptoms (NSPS) in people with self-declared sensitivity to radiofrequency electromagnetic fields (RF EMF) can be explained (across subjects) by exposure to RF EMF. Furthermore, we pioneered whether analysis at the individual level or at the group level may lead to different conclusions. By our knowledge, this is the first longitudinal study exploring the data at the individual level. A group of 57 participants was equipped with a measurement set for five consecutive days. The measurement set consisted of a body worn exposimeter measuring the radiofrequency electromagnetic field in twelve frequency bands used for communication, a GPS logger, and an electronic diary giving cues at random intervals within a two to three hour interval. At every cue, a questionnaire on the most important health complaint and nine NSPS had to be filled out. We analysed the (time-lagged) associations between RF-EMF exposure in the included frequency bands and the total number of NSPS and self-rated severity of the most important health complaint. The manifestation of NSPS was studied during two different time lags - 0–1 h, and 1–4 h - after exposure and for different exposure metrics of RF EMF. The exposure was characterised by exposure metrics describing the central tendency and the intermittency of the signal, i.e. the time-weighted average exposure, the time above an exposure level or the rate of change metric. At group level, there was no statistically significant and relevant (fixed effect) association between the measured personal exposure to RF EMF and NSPS. At individual level, after correction for multiple testing and confounding, we found significant within-person associations between WiFi (the self-declared most important source) exposure metrics and the total NSPS score and severity of the most important complaint in one participant. However, it cannot be ruled out that this association is explained by residual confounding due to imperfect control for location or activities. Therefore, the outcomes have to be regarded very prudently. The significant associations were found for the short and the long time lag, but not always concurrently, so both provide complementary information. We also conclude that analyses at the individual level can lead to different findings when compared to an analysis at group level. https://doi.org/10.1016/j.envint.2019.104948 LinkedIn: https://www.linkedin.com/in/john-bolte-0856134/
