A randomized controlled pilot trial of acceptance and commitment training (ACT) for preventing stress-related ill health among future nurses

Background: Levels of stress and burnout increase during nursing education. This development has consequences for nursing students' health, learning, competence, and interest in quality issues in health care. Design: In a randomized controlled pilot trial with a sample of 113 nursing students the effect of an intervention using techniques from acceptance and commitment training (ACT) to prevent the development of stress and burnout was evaluated. Method: The 6 × 2-hour program was compared to standard treatment (reflection seminars) post-intervention and at a three-month follow-up using longitudinal analysis of mean response profiles. Mechanisms of change were investigated using a baseline-post intervention two-mediator model. Results: The intervention resulted in increased mindful awareness and decreased experiential avoidance, as well as decreased perceived stress and burnout. Levels of mindful awareness and perceived stress were sustained at follow-up. The proposed mechanisms of change were partly supported by the data. Conclusion: This study shows that techniques from ACT might have the potential to contribute to preventing the development of stress and burnout during nursing education. However, additional studies are needed to validate these results.     

The Mentalization Scale (MentS): A Self-Report Measure for the Assessment of Mentalizing Capacity

The psychometric properties of a new 28-item self-report measure of mentalization, the Mentalization Scale (MentS), were examined in 2 studies: with a sample of employed adults and university students (N₁ = 288 + 278) and with a sample of persons with borderline personality disorder (BPD) and matched controls (N₂ = 62 + 62). Besides the MentS, both studies employed measures of attachment and the Big Five; Study 1 also included assessments of empathy and emotional intelligence. MentS whole-scale internal consistency was good in the community and acceptable in the clinical sample (α = .84 and .75, respectively). A principal components analysis of Study 1 data yielded 3 interpretable factors, or subscales: Self-Related Mentalization (MentS-S), Other-Related Mentalization (MentS-O), and Motivation to Mentalize (MentS-M). These showed acceptable reliabilities (α = .74–.79), except for MentS-M in the clinical sample (α = .60). MentS scores further exhibited a coherent pattern of correlations with cognate constructs and the Big Five, relating positively to empathy, trait and ability emotional intelligence, openness, extraversion, and conscientiousness, and negatively to attachment avoidance and anxiety, and neuroticism. Persons with BPD scored significantly lower on MentS total and MentS-S. The proposed scale is thus deemed suitable for quick, yet meaningful, assessments of mentalization in both individual differences research and clinical contexts.     

Collaborative Research, Knowledge and Emergence

We use the notion of emergence to consider the sorts of knowledge that can be produced in a collaborative research project. The notion invites us to see collaborative work as a developmental dynamic system in which various changes constantly occur. Among these we examine two sorts of knowledge that can be produced: scientific knowledge, and collaborative knowledge. We argue that collaborative knowledge can enable researchers to reflectively monitor their collaborative project, so as to encourage its most productive changes. On the basis of examples taken from this special issue, we highlight four modes of producing collaborative knowledge and discuss the possible uses of such knowledge.

A Serbian Version of Modified and Revised Experiences in Close Relationships Scale (SM–ECR–R)

We present details about the validation of the Serbian version of the Experiences in Close Relationships–Revised questionnaire modified to measure attachment in close relationships in general (SM–ECR–R). Its psychometric features were examined with 2 samples of students (N = 719 and N = 91) and 1 group of employed adults (N = 259). The results obtained in the student sample were equivalent to those obtained in validation studies worldwide, whereas in the more heterogeneous sample of employed adults, internal consistency of both avoidance and anxiety was lower and their intercorrelation was higher. Test–retest reliability was satisfactory, and relations with measures of attachment, empathy, and personality structure were meaningful. The results support the SM–ECR–R as a reliable and valid research instrument, but its internal structure and consistency might vary in different samples, depending on age, education, gender, and culture.     

The repeated insertion model for rankings: Missing link between two subset choice models

Several probabilistic models for subset choice have been proposed in the literature, for example, to explain approval voting data. We show that Marley et al.'s latent scale model is subsumed by Falmagne and Regenwetter's size-independent model, in the sense that every choice probability distribution generated by the former can also be explained by the latter. Our proof relies on the construction of a probabilistic ranking model which we label the repeated insertion model. This model is a special case of Marden's orthogonal contrast model class and, in turn, includes the classical Mallows -model as a special case. We explore its basic properties as well as its relationship to Fligner and Verducci's multistage ranking model.The authors are grateful to the National Science Foundation for grants SES98-18756 to Regenwetter and Peke, and SBR97-30076 to Regenwetter.

Putting the bits together: an information theoretical perspective on morphological processing

In this study we introduce an information-theoretical formulation of the emergence of type- and token-based effects in morphological processing. We describe a probabilistic measure of the informational complexity of a word, its information residual, which encompasses the combined influences of the amount of information contained by the target word and the amount of information carried by its nested morphological paradigms. By means of re-analyses of previously published data on Dutch words we show that the information residual outperforms the combination of traditional token- and type-based counts in predicting response latencies in visual lexical decision, and at the same time provides a parsimonious account of inflectional, derivational, and compounding processes.     

Semantic aspects of morphological processing: transparency effects in Serbian

We examined the contribution of semantics to morphological facilitation in the visual lexical decision task at two stimulus onset asynchronies (SOAs) with Serbian materials. Primes appeared in Roman or Cyrillic characters. Targets always were printed in Roman. When primes were presented at an SOA of 250 msec, decision latencies to verbal targets (e.g., VOLIM) showed greatest facilitation after inflectionally (e.g., VOLE) related primes, significantly less after semantically transparent derived primes (e.g., ZAVOLE), and less again after semantically opaque derived primes (e.g., PREVOLE). Latencies after semantically transparent and opaque derived target words did not differ at an SOA of 48 msec. Both were slower than after inflectionally related primes. Stated generally, effects of semantic transparency among derivationally related verb forms were evident at long SOAs, but not at short ones. Under alphabet-alternating conditions, magnitudes of facilitation were greater overall, but the pattern was similar. The outcome suggests that restricted processing time for the prime limits the contribution of semantics to morphological processing and calls into question accounts that posit a task-invariant semantic criterion for morphological decomposition within the lexicon.
