Adolescents' perceptions of discipline within intact families and stepfamilies

This study examined adolescents' perceptions of discipline in intact families and stepfamilies. Forty-five adolescents, ranging in age from 15 to 19 years, completed the Adolescent Discipline Perception Survey (ADPS). They responded to questions related to their own discipline experiences as well as their views on how they would discipline an adolescent. Results indicated that adolescents from intact families and stepfamilies identified loss of privileges and grounding as the primary discipline methods used by their families. In addition, adolescents from intact families and stepfamilies reported house rules and peers as the most common discipline issues. Twenty-six percent of adolescents from intact families and 44% of those from stepfamilies reported that grounding was the most severe form of punishment they had received.

New Wine in a New Bottle: Refining The Assessment of Authentic Leadership Using Exploratory Structural Equation Modeling (ESEM)

The aim of this study was to investigate the multidimensional nature of authentic leadership (AL) through the re-evaluation of the factor structure of the most commonly used scales in AL research, the Authentic Leadership Questionnaire (ALQ) and the Authentic Leadership Inventory (ALI). Results from Exploratory Structural Equation Modeling (ESEM) conducted among 538 workers of private (57,81%) and public (42,19%)? organizations provide support for the multidimensional nature of AL but also reveal excessive content overlap across subscales and an inability to properly reflect the a priori factor structure of both instruments. Further analyses enabled the identification of key items from both instruments providing a cleaner depiction of the a priori dimensionality of AL, leading to the development of an integrated optimized measure, the Authentic Leadership Integrated Questionnaire (AL-IQ). The main contribution of this study is the proposition of an alternative and optimized measure of authentic leadership that sheds light on the distinct theoretical facets of this positive leadership style. Our data suggest that the AL-IQ is a promising tool for characterizing the strengths and weaknesses of leaders and managers’ AL practices. To our knowledge, this is the first study to use a combination of classical Confirmatory Factor Analyses (CFA) and newly developed ESEM framework to assess the construct validity (factor structure, reliability, and criterion-related validity) of the two main AL measures: the ALQ and the ALI.     

Reverse production effect: children recognize novel words better when they are heard rather than produced

This research investigates the effect of production on 4.5‐ to 6‐year‐old children's recognition of newly learned words. In Experiment 1, children were taught four novel words in a produced or heard training condition during a brief training phase. In Experiment 2, children were taught eight novel words, and this time training condition was in a blocked design. Immediately after training, children were tested on their recognition of the trained novel words using a preferential looking paradigm. In both experiments, children recognized novel words that were produced and heard during training, but demonstrated better recognition for items that were heard. These findings are opposite to previous results reported in the literature with adults and children. Our results show that benefits of speech production for word learning are dependent on factors such as task complexity and the developmental stage of the learner.     

Predicting Treatment Response in Older Adults with Insomnia

This study examined potential predictors of treatment outcome in late-life insomnia. Fifty-four older adults with chronic insomnia were treated with cognitive–behavior therapy (CBT), pharmacotherapy (PCT), or combined CBT plus PCT. Pretreatment characteristics such as demographic, clinical, psychometric, and sleep variables were examined as correlates or potential predictors of treatment response. Treatment response was defined by posttreatment sleep efficiency as measured subjectively by daily sleep diary and objectively by polysomnography. The results indicate that age, insomnia duration, medical illness, and previous use of sleep medications can moderate subjective or objective treatment outcome or both of these in late-life insomnia. However, there are no reliable predictors of outcome across all treatment and assessment modalities. The implications of these findings for the treatment of insomnia in older adults seen in primary care settings are discussed.     

Eating Disorders Inventory: Assessment of its Construct Validity in a Nonclinical French Sample of Adolescents

Recent studies have questioned the appropriateness of the original Eating Disorders Inventory (EDI) in nonclinical samples of adolescents. The main objective of the present series of studies is to systematically test the construct validity of the EDI (i.e. content, factorial, convergent, discriminant and discriminative) in a nonclinical sample of French adolescents. A total sample of 1,323 adolescents was involved in these five studies. The factorial validity and the measurement invariance of the EDI were verified through confirmatory factorial analyses. Correlation and student t-tests were also used to test the convergent and discriminative validity of the EDI. Results from the first study confirmed the unsuitability of the French original EDI for young adolescents. Items were re-worded and an adaptation for adolescents was developed (EDI-A). The following four studies provided support for the factorial validity, measurement invariance, reliability, convergent validity and discriminant validity for a short form (i.e. 24 items) of the EDI-A. The present results thus provide preliminary evidence regarding the construct validity of the 24-item EDI-A for French nonclinical adolescents. Recommendations for future uses and research activities with this instrument in French speaking adolescents are outlined.

From Context to Code: Information Transfer Constrains the Emergence of Graphic Codes

Humans commit information to graphic symbols for three basic reasons: as a memory aid, as a tool for thinking, and as a means of communication. Yet, despite the benefits of transmitting information graphically, we still know very little about the biases and constraints acting on the emergence of stable, powerful, and accurate graphic codes (such as writing). Using a reference game, where participants play as Messengers and Recipients, we experimentally manipulate the function of the task (communicative or non‐communicative) and investigate whether this shapes the emergence of stable, powerful, and accurate codes for both synchronous and asynchronous modes of information transfer. Only in the Dialogue condition, where Messenger and Recipient are two different persons communicating within the same time frame (i.e., synchronously), do we consistently observe the emergence of stable, powerful, and accurate graphic codes. Such codes are unnecessary for participants in Recall, where Messenger and Recipient are the same person transferring information within the same time frame, and they fail to emerge in Correspondence, where Messenger and Recipient are two different persons communicating across time frames (i.e., asynchronously). Lastly, in the Mnemonic condition, where Messenger and Recipient are the same person at different points in time, participants achieve high accuracy but with codes that are suboptimal in terms of power and stability. Our results suggest that the rarity and late arrival of stable, powerful, and accurate graphic codes in human history largely stems from strong constraints on information transfer. In particular, we suggest that these constraints limit a code's ability to reach an adequate tradeoff between information that needs to be explicitly encoded and information that needs to be inferred from context.     

Cross-validation of the very short form of the Physical Self-Inventory (PSI-VS): invariance across genders, age groups, ethnicities and weight statuses

In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples. The present study was designed to answer these questions based on a sample of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales.
