[Design and validation of a scale to measure worry for contagion of the COVID-19 (PRE-COVID-19)]

Objective

The increase in COVID-19 cases is generating fear and concern in society, which generates an emotional response that influences the adoption of health-related behaviors. The objective of the study is to design and validate the Scale of Worry for Contagion of COVID-19 (PRE-COVID-19).

Method

The study had a descriptive cross-sectional design. The population were young people and adults who resided in the cities of Lima and Callao (Perú) during the declaration of the national health emergency due to the COVID-19 pandemic, during the period from March 16 to 27, 2020, who were recruited through a non-probability sample. The PRE-COVID-19, the WHO-Five Well-Being Index, the Generalized Anxiety Disorder Scale-2 and a single item were applied to measure the general perception of health. The scales were shared using a Google form through social networks. An internal consistency reliability analysis and structural equation models were performed, specifically confirmatory factor analysis. The recommendations of the Declaration of Helsinki and the principles that guide the ethical practice of online studies were followed.

Results

Eight hundred and sixteen young people and adults from Lima and Callao (200 men and 616 women; mean age 28.40, SD 7.10) participated. The results show a one-dimensional model with satisfactory goodness-of-fit indices: χ2 (9) = 52.00; CFI = 0.99; RMSEA = 0.09 [0.07, 0.12]; WRMR = 0.85. The λ of the model were higher than 0.50 and the reliability had an excellent value (ω = 0.90). Likewise, the convergent and discriminant validity is evident between PRE-COVID-19 and measures of anxiety, well-being and self-reported health.

Conclusion

The results indicate that the PRE-COVID-19 is a valid and reliable instrument to measure concern about the spread of COVID-19 and the emotional impact on people.

Factorial validity and invariance analysis of the five items version of Mindful Awareness Attention Scale in older adults

Objective: Mindfulness or the full attention state is a factor that contributes to the successful process of aging. This study aims to evaluate the evidence of validity, on the basis of the internal structure, convergent and discriminant validity, reliability and factorial invariance across gender, for the five items Mindful Attention Awareness Scale (MAAS-5) within a sample of older adults.Methods: The participants were 323 Peruvian older adults, consisting of 160 women and 163 men, whose average ages were 68.58 (S.D = 7.23) and 68.91 years (S.D = 7.12), respectively. In addition to the MAAS-5, the Satisfaction with Life Scale and the Patient Health Questionnaire-2 were administered.Results: The Confirmatory Factor Analysis indicates that the one-factor structure of the MAAS-5 presents adequate fit for the total sample (χ² = 11.24, df = 5, χ²/df = 2.25, CFI = .99, RMSEA = .06 [90%CI: .01, .11]; and SRMR = .025), as well as for the sub-samples of men and women. This one-factor solution presents adequate internal consistency (ω = 80 [95%CI: .76 - .82]) and it is invariant across gender. Regarding convergent validity, high scores in the MAAS are associated with a greater satisfaction with life (r = .88, p< .01 [95%CI: .85, .95]) and less depression (r = -.56, p< .01 [95%CI: -.48, -.77]) in older adults.Conclusions: The preliminary results back the use of the MAAS-5 as a self-report measure of mindfulness that has an adequate unifactorial structure that is reliable and invariant across gender for measuring the full attention state in elderly Peruvians.

Assessment of Fear of COVID-19 in Older Adults: Validation of the Fear of COVID-19 Scale

There is no information in Peru on the prevalence of mental health problems associated with COVID-19 in older adults. In this sense, the aim of the study was to gather evidence on the factor structure, criterion-related validity, and reliability of the Spanish version of the Fear of COVID-19 Scale (FCV-19S) in this population. The participants were 400 older adults (mean age = 68.04, SD = 6.41), who were administered the Fear of COVID-19 Scale, Revised Mental Health Inventory-5, Patient Health Questionnaire-2 items, and Generalized Anxiety Disorder Scale 2 items. Structural equation models were estimated, specifically confirmatory factor analysis (CFA), bifactor CFA, and structural models with latent variables (SEM). Internal consistency was estimated with composite reliability indexes (CRI) and omega coefficients. A bifactor model with both a general factor underlying all items plus a specific factor underlying items 1, 2, 4, and 5 representing the emotional response to COVID better represents the factor structure of the scale. This structure had adequate fit and good reliability, and additionally fear of COVID had a large effect on mental health. In general, women had more fear than men, having more information on COVID was associated to more fear, while having family or friends affected by COVID did not related to fear of the virus. The Spanish version of the Fear of COVID-19 Scale presents evidence of validity and reliability to assess fear of COVID-19 in the Peruvian older adult population.

Psychometric Properties of the Environmental Reward Observation Scale: Study on Its Internal Structure, Factor Invariance, and Method Effect Associated With Its Negative Items

The aim of this study was to assess the factorial structure of the scale, the method's effect associated with its negative items, its temporal invariance, and factorial invariance according to sex. For this purpose, three samples were collected, an initial sample of 200 participants, a second sample of 461 participants and a third sample of 107 participants; making a total of 768 Peruvian university students. Other instruments were applied together with the EROS scale in order to measure satisfaction with life, anxiety, stress and depression. Regarding the results, in the initial sample it was found that the original scale containing positive and negative items does adequately fit the data (RMSEA = .19; CFI = .77; TLI = .71) and also evidence was found supporting the existence of a methodological effect associated with the negative items. It was also found that version B of the scale which only has positive items data fits the data (RMSEA = .13; CFI = .96; TLI = .95). In the second sample it was found that version B still had a good fit to the data in a larger sample (RMSEA = .07; CFI = .98; TLI = .98). In addition, it was found that the scale can be considered invariant according to sex and presents validity based on other constructs. In the third sample it was found that the test-retest reliability of the scale was adequate (.70 [CI95% .593-.788]) and also evidence was found in favor of the temporal invariance of the scale. It is concluded that the scale formed only by positive items presents more robust psychometric properties and constitutes a better alternative to measure the level of reward provided by the environment.

Fear of Loneliness: Development and Validation of a Brief Scale

This research aims to develop and validate a Spanish version of The Brief Scale of Fear of Loneliness (BSFL). Participants were 1385 youth and adults, 347 from a pilot sample and 1032 from the final version, whose ages were in the range of 18 to 40 years. Two instruments, the Rosenberg Self-Esteem Scale and the De Jong Gierveld Loneliness Scale, in their Peruvian versions, were used to support the relationship with other variables. Results show that the BSFL should be interpreted as a one-dimensional measure, the same ones that were examined at the exploratory level and verified at the confirmatory moment (RMSEA < 0.08, CFI > 0.95), and its reliability is considered good (ω > 0.88). In addition, the quality of the item content was reviewed by six expert judges for relevance and validity, with Aiken’s V being greater than 0.70. It is concluded that the BSFL is a valid and precise short instrument that can be used in future research studies.

Thirty Years of Psicothema: A Bibliometric Analysis (1989-2018)

BACKGROUND

This study presents a bibliometric analysis of Psicothema as a commemoration for its 30 years of publishing (1989-2018).

METHODS

A year-, sex-, and publication language-based analysis of the journal's characteristics was carried out based on the sample of 2,396 publications. Based on that data, Lotka's law was assessed, Lawani and Subramanyam indices and cooperation networks were estimated, the Pratt index was calculated, the concentration of papers according to thematic areas and research methods was described, and citations and impact indicators were obtained according to the original articles indexed in Web of Science (1993-2018).

RESULTS

The results indicated greater participation by male authors, increased publication in English, compliance with Lotka's law, and a greater inter-institutional contribution in recent decades. There was a higher percentage of methodology/psychometrics-related work, and most of these publications used quantitative methods. The impact factor and the amount of citations reached its peak in 2018.

CONCLUSION

The characteristics of Psicothema, which is a model of scientific communication of psychology in the international context, are discussed in this study.

Single item to assess for worry for cancer: Initial evidence of validity and reliability

OBJECTIVE

To translate into Spanish and evaluate the evidence of content validity, construct validity and reliability of the Cancer Worry Chart as a single item measure of worry for cancer.

METHOD

The Spanish translation of the Cancer Worry Chart was done with the back-translation procedure. The participants were 165 healthy people with a family history of cancer who responded to the Cancer Worry Chart and the Cancer Worry Scale (CWS).

RESULTS

Translation back-translation allows a Spanish version of the Cancer Worry Chart whose content is clear, coherent and relevant (V>.70). Evidence of construct validity is reported based on 3 criteria: (a) an adequate adjustment of the one-dimensional model formed by the Cancer Worry Chart and the items of the CWS performed with the structural equations method (χ²_S-B=23.38; df=14; χ²_S-B/df=1.67; CFI=.988; RMSEA=.064); (b) a significant correlation between the Cancer Worry Chart and the CWS (r=.76 [IC95%: .68-.90]); (c) ascending averages in the CWS score as the groups formed by each response option of the Cancer Worry Chart express a greater degree of worry (F=55.72; p=.000; ω²=.57). The reliability of the Cancer Worry Chart is above what is recommended (α_{single item}=.84).

CONCLUSION

The Spanish version of the Cancer Worry Chart showed satisfactory evidence of content validity, construct validity and reliability to measure, briefly, quickly and generally, the worry for cancer in healthy people with a family history of cancer.

Measurement of the will to live in older adults: Transcultural adaptation, validity and reliability of the Will-to-Live Scale

OBJECTIVE

The Will-to-Live Scale (WTLS) is used to measure the will to live in older adults; however, there is no Spanish version. The objective of the study was to translate the WTLS into Spanish, assess its internal structure, reliability, and the correlates between WTLS and life satisfaction, resilience, and depression in older Peruvian adults.

METHOD

The participants were 235 Peruvian older adults (M=72.69, SD=6.68), evaluated between March to May 2019, selected through non-probability sampling. The WTLS, the Satisfaction with Life Scale (SWLS), the Brief Resilient Coping Scale (BRCS) and the Patient Health Questionnaire-2 (PHQ-2) were administered. Data analysis included reliability by internal consistency and structural equation models, specifically confirmatory factor analysis (AFC), to test the one-dimensional solution of the WTLS and the convergent validity of the WTLS at the latent level, by specifying a four-factor model (will to live, life satisfaction, resilience and depression).

RESULTS

Cronbach's alpha coefficient and the composite reliability index obtain values of .93 and .94, respectively. The one-dimensional structure of the WTLS was fitted to the data (χ²₍₅₎=10,067, P=.073, CFI=.999, RMSEA=.066, SRMR=.014) and showed positive associations with the SWLS (ρ=.82), and BRCS (ρ=.86), as well as negative associations with the PHQ-2 (ρ=-.66).

CONCLUSION

The WTLS in Spanish presents evidence of validity and reliability to measure the will to live in Peruvian older adults.

Psychometric properties of the Satisfaction with Job Life Scale in Portuguese workers: A systematic study based on the IRT and CFA modeling

Job satisfaction is related to better physical and mental health, as well as to factors specifically related to work. In this context, the measurement of work satisfaction is important for organizations that profess an interest in engaged and satisfied workers. Therefore, this study aims to examine the psychometric properties of the Satisfaction with Job Life Scale (SWJLS) in Portuguese workers by combining the procedures of the Classical Test Theory (CTT) and the Item Response Theory (IRT). Specifically, internal structure of the scale was studied, its reliability (consistency), correlations with other measures of wellbeing (life satisfaction, loneliness, emotional wellbeing at work, and job satisfaction) were also estimated, and finally, the sacle waqs tested for gender measurement invariance. Participants were 404 workers, 61% women and 39% men, aged between 18 and 64 years (M = 36.85; SD = 14.50). Confirmatory Factor Analysis indicated that the one-dimensional model of the SWJLS was adequate (Robust χ²(5) = 9.89, p = .078; CFI = .993; RMSEA = .049, 90% CI [.000 - .094]; SRMR = .011.) and had good internal consistency (ω = .947, 95% CI [.936, 956]; α = .947, 95% CI [.935, .955]). Subsequent analyses revealed that the scores of the SWJLS were related to other measures of job satisfaction (r = .742), job-related emotional well-being (r = .628), satisfaction with life (r = .808) and loneliness (r = -.455). Factorial invariance suggests that the structure of the SWJLS measures the same construct (satisfaction with work-life) in both female and male workers. Moreover, IRT analysis suggests that higher levels of work-life satisfaction are needed to choose the upper response options, while a very low level of work-life satisfaction is required to increase the likelihood of choosing the lower response options. In this sense, the SWJLS is useful and reliable, especially for identifying people with low levels of job satisfaction. These findings support the validity of the SWJLS and indicate that the Portuguese version is a brief instrument with good psychometric characteristics for measuring work-life satisfaction.

Does the Spanish version of the SWLS measure the same in Spain and Peru?

AIM

Satisfaction with life is a measure of protection in older adults. There lies the importance of providing quality instruments. The aim of the study was to evaluate the invariance of the life satisfaction scale (SWLS) in two samples of older adults in Spain and Peru.

METHOD

The participants were 857 older adults in Spain (mean age=68.23 years, SD=5.93) and 336 older adults in Peru (average age=72.42, SD=7.07). All multi-group confirmatory factor analyzes were estimated in Mplus 8.0.

RESULTS

The results indicate the presence of a strict invariance of the one-dimensional structure of the SWLS in samples of older adults in Spain and Peru, which allows for meaningful comparisons of latent means and covariances. Comparison of latent means showed small differences in the construct between the cultural groups.

CONCLUSIONS

The SWLS is a valid instrument for intercultural comparisons between Spanish and Peruvian population. The measurement invariance assessment contributes to a better understanding of life satisfaction in populations from different cultural contexts.

[Psychometric evidence of a brief version of the Coping Humor Scale in elderly peruvians]

INTRODUCTION

Humour plays an important role in promoting successful and healthy aging. However, its scientific study is still limited, partly due to the absence of validated tools for use in Latin America. The objective of this study was to translate the 5-item Coping with Humor Scale (CHS-5) from English to Spanish and examine the evidence of reliability and validity based on the internal, convergent, and discriminant structure of the Peruvian version of the scale.

MATERIALS AND METHOD

The participants were 236 elderly Peruvian adults (78.4% A confirmatory factor analysis, analysis of correlation (r), and reliability (α, Cronbach's alpha and ω, omega) was performed.

RESULTS

The one-dimensional model presented an adequate fit of the data (χ² = 7.72, df =5, P=.17, χ² / df = 1.54, GFI = 0.988, CFI = 0.996, NFI = 0.988, RMSEA =0. 048 [95% CI; 0.000-0.111]; and SRMR = 0.016). The reliability indexes were adequate (α= 0.86 [95% CI: 0.82-0.89] and ω = 0.89 [95% CI: 0.87-0.91]). A positive correlation was observed between the mean score of CHS-5 and satisfaction with life, and was negative with depression.

CONCLUSIONS

The CHS-5 has excellent psychometric properties, being a measure that provides valid and reliable interpretations to be used in elderly Peruvians with depression.

Validez e invarianza factorial de una medida breve de Satisfacción con la Vida Familiar

Se examinó la estructura factorial, la confiabilidad, la validez convergente y discriminante, y la invarianza factorial por sexo, de la Satisfaction with Family Life Scale (SWFLS). Los participantes fueron 804 estudiantes de primaria y secundaria de escuelas privadas de Lima, con un promedio de edad de 13.5 años (DE = 1.6). Los resultados confirman la estructura unidimensional de la escala (χ2 = 3.49, df = 5, p = 0.63; χ2/df = 0.69; GFI = 0.998; CFI = 1; NFI = 0.998; RMSEA = 0 [IC90% 0, 0.038] y SRMR = 0.007), la invarianza factorial por sexo y una consistencia interna adecuada (α = 0.84; ω = 0.84; H = 0.85). Se obtuvieron evidencias satisfactorias de validez convergente y discriminante de las SWFLS con medidas de funcionalidad familiar, bienestar subjetivo y depresión. En conclusión, la SWFLS presenta excelentes propiedades psicométricas para medir la satisfacción con la vida familiar en escolares limeños.

Translation and content validity of a brief scale of mindfulness for Peruvian adolescents

OBJECTIVE

To translate into Spanish and analyze the evidence of validity based on the content of the items in the brief version of the Mindful Attention Awareness Scale of 5 items (MAAS-5).

METHOD

An instrumental study that involved the translation to Spanish of the items of the short version of the MAAS-5 scale, using the back-translation procedure. We analyzed the evidence of validity based on the test content, with the participation of a total of 14 expert judges. The degree of clarity, coherence and relevance of the items was quantified using the Aiken V coefficient and their 95% confidence intervals using an ad hoc template developed in the MS Excel program.

RESULTS

The items of the MAAS-5 show favourable evaluations of their clarity, coherence and relevance, where all the values of V were statistically significant and greater than 0.70. On the other hand, the lower limit of 95% confidence intervals of all the items satisfies the criterion at population level (Li˃0.59).

CONCLUSION

The empirical evidence of validity based on the test content of the MAAS-5 reports that all are sufficiently relevant, coherent and clear to adequately represent the construct mindfulness, both at sample and population level. This suggests that the MAAS-5 can be a brief and useful measure to assess mindfulness. On the other hand we suggest carrying out further studies that analyze other sources of evidence of validity of the MAAS-5.

Evidencias psicométricas iniciales de una medida breve sobre preocupación por el cáncer

Objetivo: La preocupación por el cáncer está asociada con los comportamientos preventivos para la detección de esta enfermedad; sin embargo, no existe un instrumento con evidencias de validez y confiabilidad para medir este constructo en países latinoamericanos, entre ellos el Perú. Los objetivos de este estudio fueron evaluar la validez basada en la estructura interna y fiabilidad de la Cancer Worry Scale (CWS) en una muestra de personas sin diagnóstico oncológico con historia familiar de cáncer. Método: Se contó con la participación de 215 personas sanas con historia familiar de cáncer que acudían al servicio de consulta externa de dos instituciones públicas y privadas de salud de la ciudad de Chimbote con una edad promedio de 42,10 años (DT = 14,05). Para el recojo de información se utilizó una ficha sociodemográfica ad hoc y la Cancer Worry Scale. Resultados: El modelo unidimensional presentó un buen ajuste de los datos (SBχ2 (8) = 14,39; SB χ2 / df = 1,79; CFI = 0,991; SRMR = 0,025; RMSEA = 0,061 [IC90%: 0,000 -0,111]; AIC = 47,701) y una confiabilidad adecuada (ωcorregido = 0,90; IC95%: 0,88-0,92). Conclusión: Se concluye que la CWS presenta adecuadas propiedades psicométricas, siendo una medida que brinda interpretaciones válidas y fiables de la preocupación por el cáncer en el contexto peruano.
