Acculturation and clinical symptoms of schizophrenia among Latine adults in the United States

BACKGROUND

Research on acculturation and schizophrenia spectrum disorders has yielded inconsistent findings. This study aimed to clarify the influence of acculturation on symptomatology in Latine individuals with schizophrenia in the United States.

METHODS

The analysis involved cross-sectional data from Latine (n = 120) and non-Latine White (n = 60) adults with schizophrenia in San Diego, California. Participants completed the Short Acculturation Scale for Hispanics (SASH), Positive and Negative Symptom Scale, and Hamilton Depression Rating Scale in their preferred language. Univariate linear regressions were implemented to identify proxy measures as predictors of acculturation scores. Analyses of variance were conducted to analyze the relationship of SASH scores and proxy measures of acculturation to symptom severity.

RESULTS

Latine participants presented more symptom severity than non-Latine Whites. When categorized by acculturation status (Spanish-preferring, bicultural, and English-preferring), Spanish-preferring participants presented similar psychiatric symptoms to the non-Latine group and less severe symptoms than both other Latine groups. Analyses identified study language as the strongest proxy measure for the SASH. Latine participants assessed in English had significantly worse positive and depressive symptoms than those assessed in Spanish. Nativity status moderated the relationship between study language and symptomatology.

CONCLUSIONS

Findings support an association between acculturation and symptom severity among Latine individuals with schizophrenia. The use of proxy measures of acculturation may be useful in settings where time is constrained. Future research should continue to explore acculturation and symptomatology in Latine communities.

Acculturative Orientations Among Hispanic/Latinx Caregivers in the ABCD Study: Associations With Caregiver and Youth Mental Health and Youth Brain Function

Background

Population-based neuroscience offers opportunities to examine important but understudied sociocultural factors such as acculturation. Acculturation refers to the extent to which an individual retains their cultural heritage and/or adopts the receiving society's culture and is particularly salient among Hispanic/Latinx immigrants. Specific acculturative orientations have been linked to vulnerability to substance use, depression, and suicide and are known to influence family dynamics between caregivers and their children.

Methods

Using data from first- and second-generation Hispanic/Latinx caregivers in the Adolescent Brain Cognitive Development (ABCD) Study (N = 1057), we examined how caregivers' acculturative orientation affects their mental health, as well as the mental health and brain function of their children. Neuroimaging analyses focused on regions associated with self- and affiliation-based social processing (ventromedial prefrontal cortex, insula, and temporoparietal junction).

Results

We identified 2 profiles of caregiver acculturation: bicultural (retains heritage culture while adopting U.S. culture) and detached (discards heritage culture and rejects U.S. culture). Bicultural caregivers exhibited fewer internalizing and externalizing problems than detached caregivers; furthermore, youth exhibited similar internalizing effects across caregiver profiles. In addition, youth with bicultural caregivers displayed increased resting-state brain activity (i.e., fractional amplitude of low-frequency fluctuations and regional homogeneity) in the left insula, which has been linked to psychopathology; however, differences in long-range functional connectivity were not significant.

Conclusions

Caregiver acculturation is an important familial factor that has been linked to significant differences in youth mental health and insula activity. Future work should examine sociocultural and neurodevelopmental changes across adolescence to assess health outcomes and determine whether localized, corticolimbic brain effects are ultimately translated into long-range connectivity differences.

The relationship between intercultural abilities and cultural identity styles: A longitudinal cross-lagged analysis

Hybrid and alternating identity styles are dynamic strategies that members of immigrant and ethnic minority groups use to maintain multiple cultural identities. Although research shows that the two strategies predict different outcomes for cultural identity development and psychological well-being, less is known about their antecedents. The present study investigated the temporal relationship between intercultural abilities (i.e. intercultural effectiveness) and the activation of hybrid and alternating identity styles in a community sample of Filipino and Indian New Zealanders. Cross-lagged analysis indicated that intercultural abilities positively predicted the hybrid identity style and negatively predicted the alternating identity style. Cultural identity styles were not predictive of intercultural abilities over time. Multigroup analysis indicated equivalence of regression paths across ethnic groups. Findings suggest that intercultural abilities function as an antecedent of cultural identity styles.

The Views of Informal Carers' Evaluation of Services (VOICES): Toward an adaptation for the New Zealand bicultural context

OBJECTIVE

The Views of Informal Carers Experiences of Services (VOICES) instrument is a postal questionnaire that has been utilized internationally to capture the experiences of end-of-life care during the last months of life. Aotearoa/New Zealand, traditionally a bicultural society, reflects both the European worldview and that of the indigenous Māori. The Māori collectivist worldview considers whānau (extended family) support as key at the end of life and privileges "kanohi ki te kanohi" (face-to-face) meetings. In such a context, how will VOICES be received? Our pilot study was designed to test the effectiveness of an adaptation of the VOICES questionnaire in the New Zealand social setting for both Māori and non-Māori.

METHOD

Cognitive interviews were conducted with 20 bereaved whānau and family members whose relative died between January 1 and April 4, 2014, in one urban New Zealand hospital. Thematic analysis was conducted on the resulting transcripts.

RESULTS

We found that, although the questionnaire provides valuable information, administration of the current questionnaire within a bicultural context is problematic. These problems are related to its scope, cultural acceptability, structure, and content. Distribution of the VOICES questionnaire, either through the post or online, without prior consultation, also risks engaging Māori in a culturally inappropriate manner.

SIGNIFICANCE OF RESULTS

These findings will prompt revisions to both the content and research approach to implementing VOICES in a bicultural context. Recommendations include prior consultation with local indigenous communities as well as utilization of a mixed-methods approach to utilizing VOICES in a bicultural context. The cognitive interview procedures employed (adjusted for a collectivist worldview) in this study may also prove useful to indigenous groups seeking to develop or adapt questionnaires within a bicultural or multicultural context.
