Measuring parental and family efficacy beliefs of adolescents' parents: Cross‐cultural comparisons in Italy and Portugal

The goal of this study was to examine the psychometric properties of the Perceived Parental Self‐Efficacy (PPSE) and Perceived Family Collective Efficacy (PFCE) revised scales in the Portuguese and Italian contexts. To this aim two studies were conducted: the first reported the exploratory and confirmatory factor analyses with Portuguese samples, whereas the second addressed the cross‐cultural invariance of PPSE and PFCE (Portugal and Italy). Results of the first study showed the appropriate fit of the unifactorial model of both scales to Portuguese data. The invariance analyses performed in the second study attested to the PPSE and PFCE's configural, metric and scalar invariance in both countries. The correlations of PPSE and PFCE with communication, management of conflict and children's school achievement further attested to their construct and practical validity. Thus, PPSE and PFCE proved to be suitable to further use in research and psychological assessment fields.     

Invariance Properties for General Diagnostic Classification Models

In item response theory (IRT), the invariance property states that item parameter estimates are independent of the examinee sample, and examinee ability estimates are independent of the test items. While this property has long been established and understood by the measurement community for IRT models, the same cannot be said for diagnostic classification models (DCMs). DCMs are a newer class of psychometric models that are designed to classify examinees according to levels of categorical latent traits. We examined the invariance property for general DCMs using the log-linear cognitive diagnosis model (LCDM) framework. We conducted a simulation study to examine the degree to which theoretical invariance of LCDM classifications and item parameter estimates can be observed under various sample and test characteristics. Results illustrated that LCDM classifications and item parameter estimates show clear invariance when adequate model data fit is present. To demonstrate the implications of this important property, we conducted additional analyses to show that using pre-calibrated tests to classify examinees provided consistent classifications across calibration samples with varying mastery profile distributions and across tests with varying difficulties.     

Measurement invariance of the Utrecht Work Engagement Scale for Students: A study across secondary school pupils and university students

School engagement is a multidimensional construct characterized by vigour, dedication, and absorption towards academic work that is related to school achievement. This study aimed to examine the measurement invariance of a school engagement measure – the Utrecht Work Engagement Scale-Students (UWES-S) – across secondary school pupils and university students. Two samples of secondary school pupils (n = 251) and university students (n = 229) were used. The results supported the original three-factor structure (vigour, dedication and absorption) of the UWES-S instead of a two- or a one-factor structure in both samples. Evidence for the metric and scalar invariance of the measure across secondary school pupils and university students was also found. The university sample had higher scores in vigour and absorption but not in dedication. These findings demonstrate that the UWES-S can be used for developmental studies where school engagement and its relation with other variables needs to be compared across distinct educational levels.     

Personal assessment of intimacy in relationships: Validity and measurement invariance across gender

IntroductionIntimacy is central in close relationships and a variety of definitions and instruments exist in scientific literature, making this concept complex to investigate. Furthermore, gender differences were identified in the definition and experience of intimacy.ObjectivesThis study aims to confirm the three-factor structure of the personal assessment of intimacy in relationships (PAIR, Schaefer & Olson, 1981), commonly used in research and marital therapy, developed by Moore et al. (1998) and to examine the measurement equivalence of the scale across gender.MethodA confirmatory factor analysis (CFA) was performed on the responses of 313 women and 251 men in committed relationships in a French population. Measurement equivalence of the scale across gender was then conducted with the best-fitting model.ResultsThe results of CFA and post-hoc analyses revealed that the three-factor model revised with 18 items was the best fit to the data: (1) engagement (10 items), (2) communication (5 items), (3) shared friends (3 items). PAIR-18 displayed a lack of metric and scalar invariance across gender but estimated means of latent variables is not very different between the full invariant model and the unconstraint models.ConclusionNevertheless, consideration of gender differences in the construct of intimacy is very important for theoretical research on intimacy in romantic relationships and for the interventions of marital therapists based on intimacy.     

The Eyberg Child Behavior Inventory: Factorial invariance in problem behaviors across gender and age

The Eyberg Child Behavior Inventory (ECBI) assesses problem behaviors in children, and is a widely used instrument in both clinical work and research. Evidence suggests that the short ECBI version, comprising 22 items, can be reduced into the three oblique factors: Oppositional defiant behavior; Conduct problem behavior; and Inattentive behavior. The present study aimed to evaluate this three‐factor model in a Norwegian sample of 554 children, and examine multi‐group invariance across gender and age. Consistent with previous research, results confirmed a tripartite model, with the same residual covariances and cross‐loading appearing across groups. Multi‐group confirmatory factor analysis demonstrated partial measurement invariance across gender and age. Overall, findings support a meaningful comparison of the short ECBI across gender and age. The study makes a contribution to the generalizability issue of the ECBI.

Effects of barbiturates and other sedative hypnotics in pigeons trained to discriminate phencyclidine from saline.

Pigeons were trained to peck the center key (lighted white) of three response keys to turn off the center keylight and to light one of the side keys with a red keylight and the other side key with a green keylight. Five responses (fixed-ratio component) on either side key relighted the center key. Food was delivered following 10 fixed-ratio components on the red key if 1.5 mg/kg phencyclidine had been given before the session. The position of the red and green keylights on the side keys varied randomly each time they were lighted by a peck on the center key. Subsequently, increasing doses of phencyclidine, barbital, amobarbital, phenobarbital, methaqualone, methyprylon, diazepam, oxazepam, and d-amphetamine were substituted for the training dose of phencyclidine, using a cumulative dosing procedure. At low doses of the sedative hypnotics, birds pecked the keylight color associated with saline. At higher doses, birds pecked both key colors. At the highest doses of pentobarbital and amobarbital, some birds responded almost exclusively On he color associated with phencyclidine. When responding on keys of both colors occurred following administration of phencyclidine or other sedative hypnotics, this responding was controlled by key position rather than by key color.     

MATURE CONTEMPLATION

Abstract. This chapter extends biogenetic structural theory to a consideration of the biopsychological principles underlying higher phases of consciousness, particularly those attained by the systematic exploration of consciousness called contemplation. The concepts of psychic energy, flow, centeredness, energy circulation, and dreambody are explored as presented in various mystical traditions, and a model of the underlying neurophysiology is presented in terms of ergotropic-trophotropic tuning. The psychophysiology of various forms of meditation together with emergent peak experiences is examined and integrated into the ergotropic-trophotropic tuning model. Structural invariance of ergotropic-trophotropic tuning as well as invariant aspects of contemplation across different cultures and associated with different symbol systems is considered. Finally the nature and implications of Void Consciousness, God Consciousness, or Abssolute Unitary Being are examined.     

Does late preterm birth impact trunk control and early reaching behavior?

The aims of the study were to 1) verify the level of trunk control longitudinally and reaching behavior while sitting in two positions in late preterm (LPT) and full-term (FT) infants, 2) determine whether the level of trunk control relates to reaching outcomes. Twenty LPT infants and 36 infants born FT were assessed via three in-lab visits: at 6, 7, and 8 months. At each visit, the Segmental Assessment of Trunk Control (SATCo) and reaching assessment were performed, where the infants were positioned sitting in the ring and at 90° of flexion of hips, knees, and ankles. Accurate manual support to the trunk was provided in each visit. LPT infants presented a lower level of trunk control over time. LPT infants presented a higher percentage of unimanual reaches and successful grasping at 7 months' visit, and a higher number of reaches at 8 months' visit compared to FT infants. The sitting positions did not influence reaching performance. The level of trunk control relates to functional reaching strategies only in FT infants. This study might provide insights for clinicians for understanding the level of trunk control, the importance of reaching behaviors for exploration, and considering these behaviors as strategies for intervention.
