Validation of the Croatian and Lebanese Revised Illness Perception Questionnaires for Healthy People (IPQ-RH)

Adaptation and psychometric testing of the Chinese version of the Revised Illness Perception Questionnaire for cervical cancer patients

PURPOSE

Illness perception is an important factor that influences psychological distress, coping behaviors, and illness outcomes, and this factor is often assessed by the Revised Illness Perception Questionnaire (IPQ-R). Data regarding illness perception among cervical cancer patients are limited, especially in China. The study aimed to adapt and psychometrically test the Chinese version of the IPQ-R for Cervical Cancer (CIPQ-R-CC).

METHODS

This was a methodological study. Before the survey, the identity and causal subscales (originally 14 and 18 items, respectively) were adapted. Data were collected from 220 cervical cancer patients (N = 220) from June 2018 to February 2019. Psychometric properties were assessed using explanatory factor analysis, confirmatory factor analysis, Pearson correlation coefficients, one-way analysis of variance, t-tests and Cronbach's alpha coefficients.

RESULTS

Eight identity items and twenty-six causal items were included in the CIPQ-R-CC, which showed acceptable content validity (I-CVI = 0.78-1.00, S-CVI = 0.97-0.99). A five-factor solution was obtained from the cause subscale by explanatory factor analysis, and these factors explained 60.19% of the total variance. For Part III of the CIPQ-R-CC, after deleting nine items and respecifying five error covariances, the proposed seven-factor model was confirmed. There were low to moderate correlations between the latent factors (r＜0.52). Known-group validity was demonstrated in some groups with different demographic characteristics. The Cronbach's alpha coefficients were also acceptable (0.60-0.88).

CONCLUSION

The CIPQ-R-CC is a reliable and valid tool for assessing illness perception among Chinese cervical cancer patients. Future studies are needed to verify its factor structure and to confirm its theoretical connotation.

Predicting reattendance to the second round of the Maltese national breast screening programme: an analytical descriptive study

BACKGROUND

A range of barriers influence women's uptake to a first breast screening invitation. Few studies however, have examined factors associated with second screening uptake. This study follows Maltese women to explore predictors and behaviours to re-attendance, and to determine if uptake of first invitation to the Maltese Breast Screening Programme (MBSP) is a significant predictor of second screening uptake.

METHODS

A prospective study was conducted to determine factors associated with re-attendance for 100 women invited to the second MBSP round. Records of women's second attendance to the MBSP were extracted in January 2016 from the MBSP database. Data were analyzed using chi-square tests, Independent Samples t-test, Mann Whitney test, Shapiro Wilk test and logistic regression.

RESULTS

There were no significant associations for sociodemographic or health status variables with second screening uptake (p > 0.05), except breast condition (Fisher's exact test, p = 0.046). Non-attendees at second screening were most unsure of screening frequency recommendations (χ2 = 9.580, p = 0.048). Attendees were more likely to perceive their susceptibility to breast cancer (p = 0.041), believed breast cancer to be life changing (p = 0.011) and considered cues to action to aid attendance (p = 0.028). Non-attendees were in stronger agreement on mammography pain (p = 0.008) and were less likely to consider cues to action (15.4% non-attendees vs 1.4% attendees) (p = 0.017 respectively). 'Perceived barriers', 'breast cancer identity', 'causes' and 'consequences' were found to be significant predictors of second screening uptake, with 'perceived barriers' being the strongest. The inclusion of illness perception items improved the regression model's accuracy in predicting non-attendance to the second screening round (84.6% vs 30.8%). First screening uptake was found to be a significant predictor of subsequent uptake (OR = 0.102; 95% CI = 0.037, 0.283; p = 0.000).

CONCLUSIONS

Interventions to increase uptake should target first invitees since attending for the first time is a strong predictor of uptake to the second cycle. Further research is required given the small sample. Particular attention should be paid to women who did not respond to their first invite or are unsure or reluctant participants initially.

Maltese Translation and Adaptation of Champion's Health Belief Model Scale and the Revised Illness Perception Questionnaire for Breast Screening Among Maltese Women

BACKGROUND AND PURPOSE

Translating, adapting, and piloting Champion's Health Belief Model Scale for Mammography Screening (CHBMS-MS) and Revised Illness Perception Questionnaire (IPQ-R) among Maltese women.

METHODS

The Maltese questionnaire (Maltese Breast Screening Questionnaire [MBSQ]) was developed through 9 steps. Bilingual women (n = 15) completed MBSQ at 2 time points.

RESULTS

During forward-backward translations (Steps 1-4), 4 English controversial terms were raised. Twelve experts agreed on terminologies during adaptation process (Step 5). Following face validity (n = 6; Step 6), 3 items were deleted. Following reconciliation (Step 7) and proofreading (Step 8), MBSQ consisted of 121 items. Pilot testing (Step 9) showed positive correlation (CHBMS-MS = .87, IPQ-R = .85; p < .001); high Cronbach's alpha (CHBMS-MS = .93, IPQ-R = .92); overall acceptable internal consistency (CHBMS-MS = .69-.83, IPQ-R = .75-.93); and acceptable test-retest reliability correlations: CHBMS-MS (Maltese = .62-.76; English = .61-.84), IPQ-R (Maltese=.63-.82; English = .61-.91; p < .001).

CONCLUSIONS

Maltese and English scale items demonstrated high reliability and validity preliminary values.

Health beliefs, illness perceptions and determinants of breast screening uptake in Malta: a cross-sectional survey

BACKGROUND

Women's beliefs and representations of breast cancer (BC) and breast screening (BS) are salient predictors for BS practices. This study utilized the health belief model (HBM) and common-sense model (CSM) of illness self-regulation to explore factors associated with BS uptake in Malta and subsequently, to identify the most important predictors to first screening uptake.

METHODS

This cross-sectional survey enrolled Maltese women (n = 404) ages 50 to 60 at the time of their first screening invitation, invited to the National Breast Screening Programme by stratified random sampling, with no personal history of BC. Participants responded to a 121-item questionnaire by telephone between June-September 2015. Data were analyzed using descriptive statistics, chi-square tests and logistic regression.

RESULTS

There is high awareness of BC signs and symptoms among Maltese women (>80% agreement for 7 out of 8 signs), but wide variation about causation (e.g., germ or virus: 38.6% 'agree', 30.7% 'disagree'). 'Fear' was the key reason for non-attendance to first invitation (41%, n = 66) and was statistically significant across all subscale items (p < 0.05). Most items within HBM constructs (perceived barriers; cues to action; self-efficacy) were significantly associated with first invitation to the National Breast Screening Programme, such as fear of result (χ2 = 12.0, p = 0.017) and life problems were considered greater than getting mammography (χ2 = 38.8, p = 0.000). Items within CSM constructs of Illness Representation (BC causes; cyclical cancer timeline; consequences) were also significantly associated, such as BC was considered to be life-changing (χ2 = 18.0, p = 0.000) with serious financial consequences (χ2 = 13.3, p = 0.004). There were no significant associations for socio-demographic or health status variables with uptake, except for family income (χ2 = 9.7, p = 0.047). Logistic regression analyses showed that HBM constructs, in particular perceived barriers, were the strongest predictors of non-attendance to first invitation throughout the analyses (p < 0.05). However, the inclusion of illness representation dimensions improved the model accuracy to predict non-attendance when compared to HBM alone (65% vs 38.8%).

CONCLUSIONS

Interventions should be based on theory including HBM and CSM constructs, and should target first BS uptake and specific barriers to reduce disparities and increase BS uptake in Malta.
