Background: Society is witnessing two parallel phenomena: an increase in the number of mobile phone users worldwide and a growing concern about problematic smartphone use. Leading explanatory models suggest that social reward may explain some problematic smartphone use. Given that experimental evidence about the impact of social variables on problematic smartphone use is scarce, the impact of social expectancy on emotional arousal measured with skin conductance response (SCR) was analysed during instant messaging.

Method: A sample of 86 undergraduate students were randomly assigned to two groups. Experimental group participants were instructed to send a social expectation-generating message to their more active contacts in their preferred social network. After experiencing a virtual reality distraction environment, participants’ SCR was measured when they were allowed to use the smartphone and when it was withdrawn.

Results: Participants in the experimental group showed a higher SCR response than the control group. Peaks analysis also showed that peak amplitude was higher in experimental participants when their smartphones were used and withdrawn. Experimental participants also showed a longer half recovery time when using the smartphone.

Conclusions: Social expectancy is a critical variable in understanding problematic smartphone use and it should be considered in clinical contexts.

DOI: https://doi.org/10.7334/psicothema2023.193 Text:This article was originally published with errors, which have now been corrected in the online version: 1. The investigated alternative models have now been described more clearly. The method for comparing them with the original model has been correctly specified based only on Akaike’s Information Criterion (AIC) and not on the delta Comparative Fit Index, given that the models are not nested. 2. The formula for computing the critical value to which comparing the Mardia’s index for verifying if the data are multivariate normally distributed is equal to k(k+2) and not, as previously written, equal to k(k+1). 3. We have now specified that, in the Structural Equation Model, the correlations introduced between the dependent variables are correlations between the unexplained variance and thus may be described as partial correlations. 4. Finally, we have corrected the direction of the arrows of the lines from Participating, Consuming, and Expert Using observed variables toward the corresponding Cultural Capital latent variable and from Bonding and Bridging observed variables toward the corresponding social capital latent variable.

Background: The Anxiety Sensitivity Index-3 (ASI-3) is the reference instrument for measuring anxiety sensitivity. The psychometric properties of the Spanish version of the ASI-3 have been examined in university students but not in adults from the general population. Whether the ASI-3 subscales provide relevant information has not yet been examined either.

Method: The ASI-3's factor structure, internal consistency, temporal stability, and relationship with neuroticism were examined in a Spanish community sample of 919 adults.

Results: In two subsamples of participants, the ASI-3 presented a structure of three correlated factors (physical, cognitive, and social concerns) that loaded on a higher-order factor, but the three factors did not explain much item variance. The total scale and subscales of the ASI-3 showed excellent or good indices of internal consistency (alphas and omegas = .81 – .91), and adequate indices of test-retest reliability at two months ( r = .57 – .73) and the relationship with neuroticism and its facets ( r = .19 – .52).

Conclusions: The ASI-3 provides reliable, valid measures of anxiety sensitivity in Spanish adults, but its subscales are not very useful beyond the information provided by the total scale.

Background: The Intensification of Job Demands Scale (IDS) is a multidimensional instrument designed to capture the phenomenon of work intensification that characterizes modern Western societies. However, in Spain the instrument has not been validated to assess this phenomenon. The aim of this study was to examine the psychometric properties of the IDS adaptation with a heterogeneous sample of Spanish workers.

Method: The sample consisted of 722 Spanish workers (57.8% female, 42.2% male) who completed a survey between January and April 2022.

Results: A five-factor correlated model, as in the original IDS, had an optimal fit with 15 items, and displayed invariance across gender, level of education, and organizational tenure. Reliability coefficients were all satisfactory, and scale adaptation showed evidence of convergent, discriminant, and incremental validity.

Conclusions: The Spanish adaptation of the IDS is a valid, reliable measure for analyzing the phenomenon of work intensification and intensified job demands in Spain.

Background: Need for affect (NA) refers to individual differences in the motivation to approach or avoid emotion-inducing situations and activities. Prior research has demonstrated that NA is a relevant construct for understanding psychological processes related to affect. The present study aimed to adapt and validate the English version of the Need for Affect Questionnaire (NAQ), as well as the short version (i.e., the NAQ-S), to Spanish. We examined evidence of validity and reliability in the NAQ and NAQ-S scores.

Method: Study 1 ( N = 416) analyzed the psychometric properties of scores from the Spanish adaptation of the NAQ, as well as the relationships with measures of other relevant psychological constructs. Study 2 ( N = 118) tested the validity and reliability of scores from the Spanish adaptation of the NAQ-S.

Results: We found two main factors (i.e., Emotion Approach and Emotion Avoidance), and the internal consistency of both the NAQ and the NAQ-S scores, as well as their test-retest reliability, were adequate. Relationships with other measures were in line with prior research, providing positive evidence of concurrent validity.

Conclusions: Scores from both instruments showed validity and reliability, so should be considered in future research related to NA.

Background: Validity is a core topic in educational and psychological assessment. Although there are many available resources describing the concept of validity, sources of validity evidence, and suggestions about how to obtain validity evidence; there is little guidance providing specific instructions for planning and carrying out validation studies.

Method: In this paper we describe (a) the fundamental principles underlying test validity, (b) the process of validation, and (c) practical guidance for practitioners to plan and carry out sufficient validity research to support the use of a test for its intended purposes.

Results: We first define validity, describe sources of validity evidence, and provide examples where each of these sources are addressed. Then, we describe a validation agenda describing steps and tasks for planning and developing validation studies.

Conclusions: Finally, we discuss the importance of addressing validation studies from a comprehensive approach.

Antecedents: In recent years, telepractice has become widespread as an intervention strategy in Early Childhood Intervention (ECI) services. However, studies supporting its use in this field remain scarce. Because reliable instruments are needed to evaluate the perceived quality, satisfaction and the acceptability of telepractice from the families' perspective, the present study aims to report the psychometric properties of an ECI-specific instrument that includes a variety of social validity indicators that are also important and consistent with a family-centered approach.

Method: This study, with a sample of 738 families, introduces an instrument aimed at evaluating the social validity of telepractice. The scale includes the main indicators of social validity: Usability, Effectiveness; Feasibility, Utility, intervention with natural caregivers, and Future Intentions. The study aims to report its psychometric properties through a split-sample method, conducting both exploratory and confirmatory factor analysis with randomly assigned sub-samples.

Results: We found that all seven items fit into one factor measuring social validity of telepractice, with acceptable internal consistency and sensitive enough to capture differences between the type of service delivery families received.

Conclusions: In addition, the proposed instrument provides relevant information for professionals to improve the quality of service-delivery in ECI.

Background: Problems of behaviour, communication, and social interaction associated with Autism Spectrum Disorders can overwhelm parents. Disturbances in parents' psychological well-being (anxiety, depression) affect adherence to treatment, making it less effective. There is a need to investigate how to increase psychological wellbeing in parents of children with autism.

Method: An 8-week brief training programme using the Mindfulness Parenting (MP) intervention was applied to fourteen parents (6 couples and two mothers). Participants were assigned to one of two groups, both groups received the same treatment but at two different time points. Measures of anxiety (SCAARED), parental stress (PSI-4), autism severity level (AIM) and mindfulness awareness (FFMQ), were assessed.

Results: Analysis indicates that MP training increased mindfulness awareness, increasing non-judgment and reactivity, and consequently, reduced anxiety (parental, general, social), improving parent-child interaction. This improvement did not influence parents' perception of the severity of the disorder.

Conclusions: The small number of participants precludes generalisation of the results. More clinical trials are needed to demonstrate the usefulness of including these programmes in early intervention services, as well as profiles of parents who may potentially benefit from it.

Background: The pandemic affected the psychological well-being and sexuality of the population, especially among vulnerable groups such as men from sexual minorities.

Method: In Spain, a total of 320 heterosexual men and 151 sexual minority men, aged between 18 and 60, answered an ad hoc online questionnaire about sexual behavior during the lockdown.

Results: Compared to heterosexual men, during the lockdown, sexual minority men masturbated more, engaged in more sexual activities online, and had more sex with non-cohabitants. Heterosexual men had more sexual relations with their partners. Living with a partner during the lockdown predicted an improvement in sex life, especially for heterosexual men. Furthermore, the emotional impact of lockdown was a predictor of a worsening sex life regardless of sexual orientation.

Conclusions: Future interventions should take into account that men's sex lives are mediated by the emotional impact of the moment, especially among sexual minority men, since the quality of their sex life shows a weaker relationship with some of the protective variables studied (living with a partner).

Background: This study presents the adaptation and evidence of the validity of the Spanish version of the Support for Economic Inequality Scale (S-SEIS). This measure evaluates people's tendency to have positive attitudes toward economic inequality.

Method: Two correlational studies were conducted, one exploratory ( N = 619) and one confirmatory ( N = 562).

Results: S-SEIS showed good reliability in both studies. The factorial analysis showed a one-factor structure in Study 1 that was confirmed in Study 2. We also found a relationship between S-SEIS and other extensively used measures of attitudes toward inequality, such as intolerance toward inequality. S-SEIS positively correlates with belief in a just world, social dominance orientation (SDO), economic system justification (ESJ), institutional trust, and perceived democracy; it correlates negatively with intolerance toward inequality, perceived inequality, perceived warmth/competence of people in poverty and support for redistribution.

Conclusions: The current research findings suggest that S-SEIS is a valuable instrument for evaluating the support of economic inequality in Spanish samples.
