Predicting Latent Class Scores for Subsequent Analysis

Latent class regression models relate covariates and latent constructs such as psychiatric disorders. Though full maximum likelihood estimation is available, estimation is often in three steps: (i) a latent class model is fitted without covariates; (ii) latent class scores are predicted; and (iii) the scores are regressed on covariates. We propose a new method for predicting class scores that, in contrast to posterior probability-based methods, yields consistent estimators of the parameters in the third step. Additionally, in simulation studies the new methodology exhibited only a minor loss of efficiency. Finally, the new and the posterior probability-based methods are compared in an analysis of mobility/exercise.     

Compensatory internet use among individuals higher in social anxiety and its implications for well-being

The social compensation hypothesis states that the internet primarily benefits individuals who feel uncomfortable communicating face-to-face. In the current research, we tested whether individuals higher in social anxiety use the internet as a compensatory social medium, and whether such use is associated with greater well-being. In Study 1, individuals higher in social anxiety reported greater feelings of comfort and self-disclosure when socializing online than less socially anxious individuals, but reported less self-disclosure when communicating face-to-face. However, in Study 2, social anxiety was associated with lower quality of life and higher depression most strongly for individuals who communicated frequently online. Our results suggest that, whereas social anxiety may be associated with using the internet as an alternative to face-to-face communication, such a strategy may result in poorer well-being.     

Aggression-Altruism: A Scale and Some Data on Its Reliability and Validity

This article reports on the development of a scale designed to measure aggression. Using usual procedures for Thurstone scaling, a thirty-seven item Aggression Scale was created, Form A consisting of twenty items and Form B of seventeen. The test-retest reliability coefficient was .60. Results from three validity studies showed that aggression as measured by the Aggression Scale was related to perceived mild aggression training by fathers for males only, to nationalism, and to Machiavellianism.     

The Case for Mixed Emotions

How do people feel when they experience bittersweet events comprised of pleasant and unpleasant aspects (e.g., good news accompanied by bad)? Just as acids immediately neutralize bases, some have suggested that bittersweet events' pleasant aspects might neutralize their unpleasant aspects, thereby resulting in fairly neutral emotional reactions. Some contemporary theorists also contend that happiness and sadness are mutually exclusive. We review research on the alternative possibility that bittersweet events can elicit pairs of opposite‐valence, mixed emotions, with particularly close attention to the growing body of evidence that people can feel happy and sad at the same time while watching films, listening to music, and experiencing meaningful endings. We also review evidence that people sometimes experience other types of mixed emotions, including disgust accompanied by amusement and fear by enjoyment. Taken together, these data indicate that positive and negative affect are separable in experience.     

Couples’ Experiences of Hope When Participating in the Reflecting Team Process: A Case Study

Hope is believed to be influential to therapeutic change. However, no studies have explored couples’ experiences of hope during participation in a reflecting team process. This exploratory case study attends to this gap in the research literature. Three couples reported on their experiences of hope in relation to participating in the reflecting team process as part of their couple therapy. Themes related to hope were identified during three separate stages of the intervention: anticipating, participating in, and debriefing the reflecting team process. Reflecting team experiences related to hope included: seeking new perspectives, maintaining a positive momentum, identifying strengths, normalizing difficulties, presenting inspiring possibilities, providing support, highlighting growth, and strengthening resolve. These findings serve as a foundation for attending to clients’ hope as an active force during the reflecting team process.     

The failing measurement of attitudes: How semantic determinants of individual survey responses come to replace measures of attitude strength

The traditional understanding of data from Likert scales is that the quantifications involved result from measures of attitude strength. Applying a recently proposed semantic theory of survey response, we claim that survey responses tap two different sources: a mixture of attitudes plus the semantic structure of the survey. Exploring the degree to which individual responses are influenced by semantics, we hypothesized that in many cases, information about attitude strength is actually filtered out as noise in the commonly used correlation matrix. We developed a procedure to separate the semantic influence from attitude strength in individual response patterns, and compared these results to, respectively, the observed sample correlation matrices and the semantic similarity structures arising from text analysis algorithms. This was done with four datasets, comprising a total of 7,787 subjects and 27,461,502 observed item pair responses. As we argued, attitude strength seemed to account for much information about the individual respondents. However, this information did not seem to carry over into the observed sample correlation matrices, which instead converged around the semantic structures offered by the survey items. This is potentially disturbing for the traditional understanding of what survey data represent. We argue that this approach contributes to a better understanding of the cognitive processes involved in survey responses. In turn, this could help us make better use of the data that such methods provide.     

TEMPERAMENTAL ADAPTABILITY,PERSISTENCE, AND REGULARITY: PARENTAL RATINGS OF NORWEGIAN INFANTS AGED 6 TO 12 MONTHS,WITH SOME IMPLICATIONS FOR PREVENTIVE PRACTICE

There is a need for standardized measures of infant temperament to strengthen current practices in prevention and early intervention. The present study provides Norwegian data on the Cameron‐Rice Infant Temperament Questionnaire (CRITQ; J.R. Cameron & D.C. Rice, 1986a), which comprises 46 items and is used within a U.S. health maintenance organization. The CRITQ was filled out by mothers and fathers at 6 and again at 12 months as part of a longitudinal study of mental health during the first years of life (the “Little in Norway” study, N = 1,041 families enrolled; V. Moe & L. Smith, 2010). Results showed that internal consistencies were comparable with U.S. data. The temperament dimensions of persistence, adaptability, and regularity had acceptable or close‐to‐acceptable reliabilities in the U.S. study as well as in this study, and also were unifactorial in confirmatory factor analysis. These dimensions are the focus in this article. Findings concerning parents’ differential ratings of their infants on the three dimensions are reported, as is the stability of parents’ ratings of temperament from 6 to 12 months. In addition, results on the relation between temperament and parenting stress are presented. The study suggests that temperamental adaptability, persistence, and regularity may be relevant when assessing infant behavior, and may be applied in systematic prevention trials for families with infants. The inclusion of concepts related to individual differences in response tendencies and regulatory efforts may broaden the understanding of parent—infant transactions, and thus enrich prevention and sensitizing interventions with the aim of assisting infants’ development.
