Psychometric Properties of the Mental Health Continuum-Short Form: A Study of Portuguese Speaking Children/Youths

The development of measures of children and adolescents’ subjective well-being is crucial to the conceptualization and evaluation of positive mental health. The aim of this study was to investigate the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF—adolescents) across children and youths. Participants were from two different samples: 208 elementary school children (sample 1) and 216 middle school youths (sample 2). Results confirmed the three-dimensional structure of subjective well-being in both samples. The three sub-scales of the MHCSF yielded high internal consistency and results from the HTMT85 indicated discriminant validity. Measurement invariance testing across three different age groups (7–8, 9–10 and 11–14 years) confirmed the full metric and approximate scalar invariance of the MHC-SF. Full scalar invariance was achieved across gender. The study also compared the latent means for mental well-being in the three age groups, and found that the younger groups showed significantly higher levels of wellbeing. The present research study strongly suggests that the MHC-SF (adolescents) is an appropriate instrument to measure the positive mental health and well-being of children and pre-adolescents as multidimensional construct.     

‘For Fun’: (De) Humanizing Gisberta—The Violence of Binary Gender Social Representation

In 2006, Gisberta Salce Júnior died inside of a pit, in an abandoned building, after being tortured for 3 days by a group of teenagers, in Porto, Portugal. Gisberta was a transgender woman who had moved to Portugal from Brazil in the 1980’s. In this paper, we explore the media coverage of her death as an illustrative case of existing social representations of gender, resulting in two main findings: that even those who are seen as communities of support and recognition perpetuate discourses of gender binary norms, and that the only apparent possibility to humanize and transcend these norms is materialized in artistic performance and production, which allows for a more emotional connection to the ‘subject’ as a human individual rather than a mere transgression. The analysis of articles about Gisberta revealed that there is a very strong social representation of gender as a binary, consisting rigidly of female and male poles. As such, the social representation of those individuals who transgress this binary, embodying alternative performances of gender, as was the case with Gisberta, is reduced to their sexuality, their embodiment of something other than the gender binary. Different perspectives were identified: media, the courtroom, the teenagers, LGTB activists and the arts. Through this analysis and division, it was possible to conclude that these binary norms are embedded to the extent that they permeate even the discourses of those who tend to speak for trans people, in such a way that it seems almost impossible to escape them, with one powerful exception: that of artistic expression, which seems to be the only topos from which true recognition is achieved. This case is an extreme example of the necessity to transcend gender norms and allow for recognition of individuals as such.     

Choice biases in no-sample and delay testing in pigeons (Columba livia)

Animal Cognition - In experimental tasks that involve stimuli that vary along a quantitative continuum, some choice biases are commonly found. Take, for instance, a matching-to-sample task where...     

Equivalence of human odometry by walk and run is indifferent to self-selected speed

Humans and other animals can measure distances nonvisually by legged locomotion. Experiments typically employ an outbound measure (M) and an inbound report (R) phase. Previous research has found distance reproduction to be maximally accurate, when gait symmetry and speed of M and R are of like kind: Successful human odometry manifests at the level of the M-R system. In the present work, M was an experimenter-set distance produced by a blindfolded participant using a primary gait (walk, run). R was always by walk. Fast and slow versions of walk and run were adopted by participants, such that when M was fast R was slow, and vice versa. Distance was underestimated when M was slower than R and overestimated when M was faster than R. However, the pattern of participant-adopted velocities indicated that it was the instructions, not the speed as such, that yielded the pattern of results. The results are interpretable through a dynamical perspective and indicate speed is an imperfection parameter acting on the attractors of the M-R system.     

Fragile visual short-term memory is an object-based and location-specific store

Fragile visual short-term memory (FM) is a recently discovered form of visual short-term memory. Evidence suggests that it provides rich and high-capacity storage, like iconic memory, yet it exists, without interference, almost as long as visual working memory. In the present study, we sought to unveil the functional underpinnings of this memory storage. We found that FM is only completely erased when the new visual scene appears at the same location and consists of the same objects as the to-be-recalled information. This result has two important implications: First, it shows that FM is an object- and location-specific store, and second, it suggests that FM might be used in everyday life when the presentation of visual information is appropriately designed.     

Experiential avoidance and self‐compassion in chronic pain

The present study investigates the role of coping, experiential avoidance, and self‐compassion on psychological distress prediction (i.e., depression, anxiety, and stress symptoms). A battery of self‐report questionnaires was used to assess coping, experiential avoidance, self‐compassion, and psychological distress in 103 adults with chronic pain from Portuguese primary health care units. Hierarchical regression analyses were performed and showed that experiential avoidance and self‐compassion are the factors that mostly explain psychological distress. Our results suggest that when people with chronic pain are willing to remain in contact with particular private experiences without attempting to control them, they reported less depression, anxiety, and stress. Implications for clinical practice were discussed, suggesting the importance of helping people with chronic pain to increase their willingness to pain rather than avoiding it.     

Joint stimulus control in a temporal discrimination task

The ability to identify stimuli that signal important events is fundamental for an organism to adapt to its environment. In the present paper, we investigated how more than one stimulus could be used jointly to learn a temporal discrimination task. Ten pigeons were exposed to a symbolic matching-to-sample procedure with three durations as samples (2, 6, and 18 s of keylight) and two colors as comparisons (red and green hues). A 30-s intertrial interval (ITI), illuminated with a houselight, separated the trials. Both the houselight and the sample keylight could control responding, so two tests were run to assess how these stimuli influenced choice. In the no-sample test, the keylight was not presented; in the dark-ITI test, the houselight was not illuminated. Results suggest that both houselight and keylight controlled choice, and with the exception of one animal, the more a pigeon relied on one of these stimuli, the less it appeared to rely on the other.     

Personality assessment in DSM-5: empirical support for rating severity, style, and traits

Despite a general consensus that dimensional models are superior to the categorical representations of personality disorders in DSM-IV, proposals for how to depict personality pathology dimensions vary substantially. One important question involves how to separate clinical severity from the style of expression through which personality pathology manifests. This study empirically distinguished stylistic elements of personality pathology symptoms from the overall severity of personality disorder in a large, longitudinally assessed clinical sample (N = 605). Data suggest that generalized severity is the most important single predictor of current and prospective dysfunction, but that stylistic elements also indicate specific areas of difficulty. Normative personality traits tend to relate to the general propensity for personality pathology, but not stylistic elements of personality disorders. Overall, findings support a three-stage diagnostic strategy involving a global rating of personality disorder severity, ratings of parsimonious and discriminant valid stylistic elements of personality disorder, and ratings of normative personality traits.     

Attachment and coparenting representations in men during the transition to parenthood

Coparenting is based on parents’ representations of themselves as coparents. Attachment theory can be a useful framework to understand the way that different coparenting representations are developed during the transition to parenthood. This study aimed to analyze the association between men's attachment and coparenting representations at the first trimester of pregnancy and from the first trimester of pregnancy to 6 months’ postpartum. A sample of 86 men was recruited and completed self-report measures of attachment and coparenting representations at the first and third trimester of pregnancy and at 1 and 6 months’ postpartum. At the first trimester of pregnancy, higher attachment avoidance was associated with higher lack of coparenting support. From the first trimester of pregnancy to 6 months’ postpartum, higher attachment avoidance was associated with (a) a steeper increase on lack of coparenting support, (b) an increase on coparenting conflict (while low attachment avoidance was associated with a decrease), and (c) a lower decrease on coparenting disagreement. This study may contribute to coparenting research by showing new evidence on attachment theory as a useful framework to understand how different coparenting representations are developed in men during the transition to parenthood.     

Mediators of physical activity behavior change: a multivariate approach

OBJECTIVE: Using a multivariate extension of the Baron and Kenny (1986) mediation framework, we examined the simultaneous effect of variables hypothesized to mediate the relationship between a motivationally tailored physical activity intervention, and 6-month physical activity behavior in 239 healthy, underactive adults (M age = 47.5; 82% women). DESIGN: Participants were randomly assigned to (a) print-based feedback; (b) telephone-based feedback; or (c) contact control. MAIN OUTCOME MEASURES: Psychosocial variables, including self-efficacy, decisional balance, and processes of change. RESULTS: All mediation criteria were satisfied for both intervention arms. A moderate indirect effect of print (0.39, 95% CI = 0.21, 0.57) was found due to increases in behavioral processes (0.54, 95% CI = 0.29, 0.80) being attenuated by decreases due to cognitive processes (-0.17, 95%CI = 0.31,-.03). A moderate indirect effect was observed for telephone (0.47, 95% CI = 0.28, 0.66), with increases due to behavioral processes (0.61, 95% CI = 0.34, 0.87) attenuated by decreases due to cognitive processes (0.15, 95% CI = -0.27, -0.02); self-efficacy and decisional balance mediational paths did not attain statistical significance. CONCLUSIONS: These findings highlight the importance of studies that deconstruct the theoretical components of interventions to determine which combination produces the greatest behavior changes at the lowest cost.
