The spiritual well-being questionnaire: Testing for model applicability, measurement and structural equivalencies, and latent mean differences across gender

Fisher (1998) proposed a spiritual well-being model, comprising primary factors for the domains of personal, communal, environmental and transcendental well-being, that cohere to form a single higher order or global spiritual well-being dimension. In line with this model, Gomez and Fisher (2003) published the Spiritual Well-Being Questionnaire (SWBQ), with scales for measuring personal, communal, environmental and transcendental spiritual well-being. This study used multi-group confirmatory factor analysis (CFA) to examine gender equivalencies of the measurement and structural models of the SWBQ, and the latent mean in the four SWBQ factors. A total of 3101 females and 1361 males, with age ranging from 15 to 32 years, completed the SWBQ. The statistical fit results supported the invariance of the measurement model, and some aspects of the structural model. The practical fit indices results provided support for the invariance of both the measurement and structural models. The results also showed little gender differences. Together, these findings support gender equivalencies for the SWBQ.     

Item response theory analyses of adult self-ratings of the ADHD symptoms in the Current Symptoms Scale

The graded response model, which is based on item response theory, was used to evaluate the psychometric properties of adult self-ratings (N = 852) of the attention deficit/hyperactivity disorder inattention, hyperactivity, and impulsivity symptoms presented in the Current Symptoms Scale. This scale has four ordered response categories. The results for the discrimination parameters showed that all symptoms were generally good for discriminating their respective latent traits. For virtually all symptoms, their threshold values showed that they were especially good at representing the appropriate traits from around the mean trait level onward. The item information function values for most symptoms indicated reasonable reliability from approximately the mean trait level onward. All these findings are new and extend existing psychometric information for adult self-ratings of the attention deficit/hyperactivity disorder symptoms in the Current Symptoms Scale.     

Assessing women's responses to sexual threat: validity of a virtual role-play procedure

This study evaluated the validity of a role-play procedure that uses virtual reality technology to assess women's responses to sexual threat. Forty-eight female undergraduate students were randomly assigned to either a standard, face-to-face role-play (RP) or a virtual role-play (VRP) of a sexually coercive situation. A multimethod assessment strategy was used to evaluate the efficacy of the role-play procedure in creating a realistic and immersive situation. Consistent with our hypotheses, women in the VRP condition exhibited greater negative affect and immersion than women in the RP condition. In addition, the level of assertive refusal in the VRP, but not the RP, condition differentiated between women with and without a prior history of sexual victimization. These findings provide evidence of the validity of a virtual role-play procedure for assessing women's responses in sexually threatening situations.     

Cohort Differences in Personal Goals and Life Satisfaction in Young Adulthood: Evidence for Historical Shifts in Developmental Tasks

This study investigated the influence of changing socio-historical conditions on personal goals in young adulthood. It was hypothesized that socio-historical changes related to individualization have resulted in shifts in goal pursuit. Participants from three birth cohorts reconstructed their important goals when they were 20 years old. Members of the oldest cohort were born between 1920 and 1925. Members of the middle cohort were born between 1945 and 1950. Members of the youngest cohort were born between 1970 and 1975. Goal content, the degree to which goals were perceived as being shared by members of the same cohort (social sharedness), perceived control over goal attainment, success in attainment, and life satisfaction at age 25 were measured in a retrospective study. Results show consistent shifts over time. Whereas members of older cohorts mentioned goals related to classical developmental tasks, members of younger cohorts mentioned more individualistic, self-related goals and goals related to education. The processes through which goal pursuit influenced life satisfaction also changed. Perceived social sharedness of goals was a direct predictor of life satisfaction for the oldest cohort. For the younger cohorts, perceived control over goal attainment influenced success which in turn influenced life satisfaction. These changes support the contention that developmental tasks and processes are historically variant.     

A hierarchical approach for fitting curves to response time measurements

Understanding how response time (RT) changes with manipulations has been critical in distinguishing among theories in cognition. It is well known that aggregating data distorts functional relationships (e.g., Estes, 1956). Less well appreciated is a second pitfall: Minimizing squared errors (i.e., OLS regression) also distorts estimated functional forms with RT data. We discuss three properties of RT that should be modeled for accurate analysis and, on the basis of these three properties, provide a hierarchical Weibull regression model for regressing RT onto covariates. Hierarchical regression model analysis of lexical decision task data reveals that RT decreases as a power function of word frequency with the scale of RT decreasing 11% for every doubling of word frequency. A detailed discussion of the model and analysis techniques are presented as archived materials and may be downloaded from www.psychonomic.org/archive.     

The overlap model: a model of letter position coding

Recent research has shown that letter identity and letter position are not integral perceptual dimensions (e.g., jugde primes judge in word-recognition experiments). Most comprehensive computational models of visual word recognition (e.g., the interactive activation model, J. L. McClelland & D. E. Rumelhart, 1981, and its successors) assume that the position of each letter within a word is perfectly encoded. Thus, these models are unable to explain the presence of effects of letter transposition (trial-trail), letter migration (beard-bread), repeated letters (moose-mouse), or subset/superset effects (faulty-faculty). The authors extend R. Ratcliff's (1981) theory of order relations for encoding of letter positions and show that the model can successfully deal with these effects. The basic assumption is that letters in the visual stimulus have distributions over positions so that the representation of one letter will extend into adjacent letter positions. To test the model, the authors conducted a series of forced-choice perceptual identification experiments. The overlap model produced very good fits to the empirical data, and even a simplified 2-parameter model was capable of producing fits for 104 observed data points with a correlation coefficient of .91.     

The association of depression and sense of belonging with suicidal ideation among older adults: applicability of resiliency models

Suicide among older people, especially men, is a significant problem. In this study the applicability of the compensatory, the risk-protective, the challenge, and the protective-protective models of resiliency for the prediction of suicidal ideation from depression (the risk factor) and sense of belonging to the community (the protective factor) was investigated. A total of 351 retired Australians (130 males and 221 females), with a mean age of 71.31 years (SD = 7.99), completed the Zung Depression Scale, the suicide subscale of the General Health Questionnaire, and the Sense of Belonging Instrument. When sense of belonging (psychological) was the protective factor, results indicated support for the risk-protective model for men and women, and for the compensatory model for women only. In contrast, when sense of belonging (antecedents) was the protective factor, support was evident for the compensatory model for men and women, and for the challenge model for women only. Results indicate that interventions should be developed to enhance sense of belonging among aging adults.     

Reconsolidation of episodic memories: a subtle reminder triggers integration of new information

Recent demonstrations of "reconsolidation" suggest that memories can be modified when they are reactivated. Reconsolidation has been observed in human procedural memory and in implicit memory in infants. This study asks whether episodic memory undergoes reconsolidation. College students learned a list of objects on Day 1. On Day 2, they received a reminder or not, and then learned a second list. Memory for List 1 was tested immediately on Day 2 (Experiment 2) or on Day 3 (Experiment 1). Although the reminder did not moderate the number of items recalled from List 1 on either day, subjects who received a reminder incorrectly intermixed items from the second list when recalling List 1 on Day 3. Experiment 2 showed that this effect does not occur immediately and thus is time-dependent. The reminder did not affect memory for List 2 on Day 3 (Experiment 3), demonstrating that modification occurred only for the original memory (List 1). The study demonstrates the crucial role of reminders for the modification of episodic memory, that reconsolidation of episodic memory is time-dependent, and, in contrast to previous reconsolidation findings, that reconsolidation is also a constructive process, one that supports the incorporation of new information in memory.     

A model of the go/no-go task

In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of 3 experimental tasks is presented. Prior research has questioned whether the underlying core-information processing is different for the 2 variants of a task or whether they differ mostly in response demands. The authors examined 4 different diffusion models for the go/no-go variant of each task along with a standard diffusion model for the 2-choice variant (R. Ratcliff, 1978). The 2-choice and the go/no-go models were fit to data from 4 lexical decision experiments, 1 numerosity discrimination experiment, and 1 recognition memory experiment, each with 2-choice and go/no-go variants. The models that assumed an implicit decision criterion for no-go responses produced better fits than models that did not. The best model was one in which only response criteria and the nondecisional components of processing changed between the 2 variants, supporting the view that the core information on which decisions are based is not different between them.
