Background: The aim of this study was to evaluate the psychometric properties, differential item functioning, factorial invariance, and convergent validity of the Spanish version of the Herth Hope Index (HHI) in patients with cancer.

Method: Exploratory and confirmatory factor analyses were conducted to explore the scale, dimensionality, functioning of items, test for strong measurement invariance across sex, age, tumor site, and expected survival, and an extended structural equation model to assess external validity in a cross-sectional, multicenter, prospective study of 863 cancer patients from 15 Spanish hospitals.

Results: The results do not support the original 3-factor scale but instead suggest a one-factor structure, which explained 62% of the common variance. Scores from the unidimensional structure exhibited satisfactory reliability (ω = .88). A strong invariance solution demonstrated excellent fit across sex, age, tumor site, and survival. HHI exhibited substantial associations with resilience coping strategies and spiritual well-being.

Conclusions: The findings of our study contribute to the diversity of earlier empirical findings regarding the construct of hope. Despite this, our results indicate that the Spanish version of the HHI is a short, easy-to-administer, valid, reliable tool for evaluating cancer patients’ levels of hope.

Background: Political extremism is one of the main threats to democratic societies and it has been related to socioeconomic threats like COVID-19. We argue that socioeconomic threat perceptions increase Monopoly on Truth (MoT), a tendency to conceive personal values as undeniable truths that are worthy of being imposed. MoT will then prompt a rise in extremist intentions.

Method: These hypotheses were tested in two experimental designs ( N = 274 & 484). Study 1 manipulated socioeconomic threat, while Study 2 added a manipulation of the emotional appraisal of that threat.

Results: In Study 1, MoT scores were significantly different and higher in the high-threat condition. In Study 2, threat levels did not cause statistically significant differences when emotional appraisal of the threat was manipulated, with anger causing MoT to increase. Study 2 also showed that MoT works as a precursor of extremist intentions.

Conclusions: Socioeconomic threats and their emotional appraisals raise MoT and, indirectly, extremism. Beyond deepening our understanding of the causes of MoT, the current findings highlight the implications of different narratives framing socioeconomic crises that may become a facilitating factor of extremism.

Background: Neuropsychiatric symptoms (NPS) are a psychopathological dimension of neurodegenerative diseases, consisting of personality changes, behavioral disorders, and alterations in basic functions such as appetite or sleep, among others. The aim of this study was the construction and validation of a screening test to identify these NPS associated with neurodegenerative pathologies in preclinical and prodromal stages, based on the ISTAART criteria for Mild Behavioral Impairment (MBI).

Method: The sample consisted of 206 subjects over 55 years old (117 cognitively healthy, 89 with Mild Cognitive Impairment). 69% were women, the mean age was 77 years ( SD = 10.58).

Results: The new scale consists of 19 items and exhibited a one-dimensional structure. Confidence was excellent (α = .94 and Ω = .97) and there was evidence of convergent validity with the MBI-C test ( r = .88) and the NPI-Q ( r = .82). In addition, the scale demonstrated good sensitivity (.88) and specificity (.80).

Conclusions: The scale allows evaluation of NPS in DCoL. It exhibits good psychometric properties and makes a useful tool in early diagnosis of neurodegenerative pathologies.

Background: Body compassion is a protective factor in the field of eating disorders (ED) that has been associated with higher body appreciation and lower body shame. However, more studies are needed in order to disentangle the protective role of compassion in regard to the risk of ED. The study’s aims were to (1) analyze the psychometric properties of the Spanish adaptation of the Body Compassion Scale (BCS) and (2) determine whether body appreciation and body shame were mediators in the relationship between body compassion and the risk of ED.

Method: 288 women (range: 18-40 years old; M = 24.65 ± 5.02) from the general Spanish population completed online questionnaires.

Results: The Spanish adaptation of the BCS was reliable and valid. Results of a serial and parallel mediation model confirmed the protective role of body compassion and body appreciation on body shame and the risk of ED, accounting for 68.88% of the variance.

Conclusions: Findings indicate that women who present higher body compassion tend to show higher body appreciation, which in turn leads to lower internal body shame and lower risk of ED. These results support the need to develop a positive and compassionate relationship with one’s body, in order to prevent ED.

Background: Following experts' recommendations for a phenomenological approach to suicidal behavior, this study opted to focus on the life-protecting beliefs and values expressed by people in acute suicidal crisis.

Method: 61 adults hospitalized in psychiatric emergency for suicidal crises were assessed in terms of reasons for living (RFL) and suicidality. Multiple correspondence analysis was used to discern groups of patients based on their RFL profiles. Group differences on suicidality were further examined.

Results: 4 groups of patients were observed, emerging from RFL differences in "Survival and Coping Beliefs", "Fear of Social Disapproval", "Responsibility to Family" and "Child-Related Concerns". Profiles varied by gender but not age. We further observed that "Survival and Coping Beliefs" and "Moral Objections" are weakened during an acute suicidal crisis.

Conclusions: These findings underline the clinical utility of evaluating RFL during a suicidal crisis, and that RFL may be useful to personalize case formulation during an emergency intervention. They could further increase therapeutic communication by connecting the individual to key psychological resources. Longitudinal studies are necessary to evaluate how the different groups identified in this study may yield specific post-emergency trajectories connected to specific clinical needs.

Background: In this study, we examined whether a persuasive message in favor of a pro-environmental proposal could influence attitude change through a self-validation process when individuals were told that the source of the proposal belonged to their ingroup (vs. their outgroup).

Method: Participants read a message that advocated for the use of solar power. Immediately following the message, participants were asked to list their thoughts regarding the persuasive proposal. A thought favorability index was created for each participant. Following the thought-listing task, participants received the experimental manipulation (i.e., ingroup vs. outgroup source) based on the minimal group paradigm, after which they reported their attitudes towards the proposal.

Results: A regression analysis showed the predicted interaction between thought favorability and type of source (i.e., ingroup vs. outgroup) on attitudes towards the solar power proposal. According to our expectations, thought favorability was a better predictor of attitudes for participants in the ingroup (vs. outgroup) source condition.

Conclusions: Attitudes can be polarized as a function of ingroup versus outgroup differentiation through a self-validation process.

Background: There is a significant gap in scientific understanding about suicide among people experiencing homelessness (PEHs).

Method: This seven-year longitudinal study examined a cohort of 154 PEHs. In 2015, clinical assessments were conducted, including an evaluation of suicide risk, with data on causes of death collected from public health service records in 2022.

Results: Over the course of seven years, 14.3% of the sample passed away at an average age of 52.6 years. The leading causes of death were cancer, suicide, and accidental overdose. Participants who experienced violence had a higher number of suicide attempts and scored higher on the suicidal ideation scale. The most significant factors associated with mortality were prior suicide attempts and suicidal ideation.

Conclusions: This study underscores the importance of suicide risk scale scores as the primary predictor of mortality. It emphasizes the need for further longitudinal research on suicide among PEHs and the development of specific programs to prevent suicide within this population. An approach combining structural and individual perspectives is suggested, considering appropriate housing policies and mental health care.

Background: Applying a three-level meta-analysis, the goal of our investigation was to examine the relationship between parental homework involvement and students’ achievement, and to investigate whether certain study features could have resulted in the inconsistent results relating to this relationship from prior studies.

Method: We identified a total of 28 studies (32 independent samples) with 252 effect sizes for a total of 378222 participants.

Results: Our meta-analysis revealed an overall weak negative relationship between parental homework involvement and students’ achievement ( r = −0.064, p < 0.001). The overall relationship was moderated by the dimension of parental homework involvement. Specifically, students’ achievement was positively related to autonomy support, but largely unrelated to content support, parental control, frequency, and mixed. Additionally, the overall relationship was moderated by achievement measure, grade level, and parent gender.

Conclusions: Given that parental autonomy support was the only dimension that was positively related to students’ achievement, it would be important to conduct qualitative research that provides longitudinal descriptions of parent-child interactions relating to homework tasks as children make their transition from elementary to middle and high school.

Background: Adolescence is an important period for development, when psychological problems may appear, including suicidal behavior. Experiencing Stressful Life Events (SLEs) is associated with increased risk of such problems, although the impact of distinct types of SLEs has seldom been examined. This study aims to analyze associations between different SLEs, psychological problems, subjective well-being, and suicidal behavior in adolescents. A new instrument was developed—the Stressful Life Events Checklist for Adolescents (SLECA)—where SLEs were classified as: minor/major, dependent/independent, interpersonal/non-interpersonal, and chronic/episodic.

Method: Two waves of data collection were included. Wave 1 involved 5,610 adolescents whereas wave 2 involved 2,312 adolescents.

Results: Major dependent interpersonal episodic SLEs were strongly associated with externalizing problems. Major dependent non-interpersonal episodic SLEs showed the highest association with attention-deficit/hyperactivity problems. Major independent chronic SLEs were associated with low subjective well-being, and internalizing problems. Peer problems and academic SLEs were associated with psychological problems and low subjective-well-being. Controlling for mental health variables, suicidal behavior was related to major independent chronic SLEs and to those linked to victimization and sexuality- related problems.

Conclusions: The SLECA is a useful instrument for assessing SLEs in adolescents, unravelling the interrelations between SLEs, mental health, and suicidal behavior.

Background: The Self-Absorption Scale (SAS) is one of the few instruments that measure dysfunctional self-focused attention or self-absorption, a transdiagnostic factor of vulnerability to various emotional disorders. The internal structure of the Spanish version of the SAS and its relationship with other variables have not been examined, nor has whether its subscales provide relevant information. These were the two goals of the present study.

Method: The factor structure of the SAS, its internal consistency, and its relationship with depression and post-traumatic stress were analyzed in a Spanish community sample of 519 adults.

Results: The SAS presented a symmetrical bifactor structure with a general factor of self-absorption that explained most of the variance in the items and two specific factors of private and public self-absorption. The total scale and the two subscales of the SAS exhibited excellent, good or adequate reliability coefficients (alphas/omegas = .70 – .88) and correlated with depression and post-traumatic stress ( r = .34 – .46).

Conclusions: The SAS provides reliable, valid measures of dysfunctional self-focused attention in Spanish adults, but its Private and Public Self-absorption subscales are not much more useful than the information provided by its total scale.
