Cross-cultural adaptation and psychometric evaluation of the social frailty scale in Iranian older adults.

BACKGROUND: Social frailty is a holistic concept encompassing various social determinants of health. Considering its importance and impact on health-related outcomes in older adults, the present study was conducted to cross-culturally adapt and psychometrically evaluate the Social Frailty Scale in Iranian older adults in 2023. METHODS: This was a methodological study. The translation and cross-cultural adaptation of the Social Frailty Scale 8-item (SFS-8) was conducted according to Wild's guideline. Content and face validity were assessed using qualitative and quantitative methods. Then, 250 older adults covered by comprehensive health centers were selected using multistage random sampling. Participants completed the demographic questionnaire, the Abbreviated Mental Test score, the SFS-8, and the Lubben Social Network Scale. Construct validity was assessed by principal component analysis (PCA) and known-group comparisons. The Mann‒Whitney U test was used to compare social frailty scores between the isolated and non-isolated older adults. Internal consistency, equivalence, and stability were assessed using the Kuder-Richardson method, the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and the minimum detectable change (MDC). The ceiling and floor effects were also assessed. The data were analyzed using JASP 0.17.3. RESULTS: The ratio and index of content validity and the modified kappa coefficient of all the items were 1.00. The impact score of the items was greater than 4.6. PCA identified the scale as a single component by removing two questions that could explain 52.9% of the total variance in the scale score. The Persian version of the Social Frailty Scale could distinguish between isolated and non-isolated older adults (p < 0.001). The Kuder-Richardson coefficient, ICC, SEM, and MDC were 0.606, 0.904, 0.129, and 0.358, respectively. The relative frequencies of the minimum and maximum scores obtained from the scale were 34.8 and 1.2, respectively. CONCLUSIONS: The Persian version of the Social Frailty Scale (P-SFS) can be used as a valid and reliable scale to assess social frailty in Iranian older adults.

Development and preliminary psychometric investigation of the German Satisfaction with Comprehensive Cancer Care (SCCC) Questionnaire.

PURPOSE: The assessment of patient satisfaction during treatment is essential to provide patient-centered high-quality cancer care. Nevertheless, no German instrument assesses patient satisfaction with comprehensive cancer care, which not only includes oncological treatment, but also interpersonal quality of care as well as psychosocial support services. Based on the French REPERES-60, we developed the German Patient Satisfaction with Comprehensive Cancer Care (SCCC) questionnaire. METHODS: The REPERES-60 was translated and the items were adapted to make it applicable to the German healthcare system and across different tumor entities. Scales of the resulting instrument were extracted via principal axis factoring (PAF). Subsequently, we investigated the reliability (Cronbach's Alpha, CA), discriminatory power (corrected item-scale correlations) and convergent validity (pre-specified correlations of the SCCC with different outcomes). RESULTS: The SCCC consisted of 32 items which were subsequently tested among a sample of 333 patients across different tumor entities (response rate: 47%). Average age was 59 years (standard deviation: 14), 63% were male. PAF revealed four multi-item scales named Competence, Information, Access and Support accounting for 71% of the variance. Two single-items scales assess global satisfaction with medical and psychosocial care, respectively. CA across the multi-item scales ranged from .84 to .96. Discriminatory power was sufficiently high, with all r ≥ .5. Convergent validity was largely verified by negative associations of the four multi-item scales with depressive/anxious symptomatology (r ≥ - .18, p < .01) and fatigue/overall symptom burden (r ≥ - .14, p < .01). CONCLUSION: We developed a tool to assess patient satisfaction with comprehensive cancer care in Germany. The SCCC showed satisfactory psychometric properties. Further studies are needed to verify these preliminary findings.

Czech Version of the Spiritual Well-Being Scale: Evaluation and Psychometric Properties.

Spirituality and spiritual well-being are connected with many areas of human life. Thus, especially in secular countries, there is a need for reliable validated instruments for measuring spirituality. The Spiritual Well-Being Scale is among the world's most often used tools; therefore, the aim of this study was its psychometrical evaluation in the secular environment of the Czech Republic on a nationally representative sample (n = 1797, mean age: 45.9 ± 17.67; 48.6% men). A non-parametric comparison of different sociodemographic groups showed a higher disposition for experiencing spirituality among women, older people, and divorced persons. Based on confirmatory factor analysis, negatively worded items were excluded using a polychoric correlation matrix. The new version of the scale consisting of 11 items had good internal consistency (Cronbach's α = 0.85; McDonald's ωt = 0.91). The two-factor model of this shortened version, with factors corresponding to the Religious and the Existential subscales of the Spiritual Well-Being Scale, shows a satisfactory fit with the data, where the loadings of all items ranged from medium to high. Thus, this study offered a new version of the tool, convenient for measuring spiritual well-being in secular conditions.

Towards patient-centred cancer care: cross-cultural validity and responsiveness of the Turkish Integrated Palliative care Outcome Scale.

BACKGROUND: A valid measure to describe the most important needs and concerns of people with life-threatening illnesses is missing in Cyprus. Our aim was to adapt and test the cross-cultural validity and responsiveness of the Integrated Palliative care Outcome Scale (IPOS) in a cohort of Turkish speaking cancer patients. METHODS: The IPOS (English) patient-reported measure was translated into Turkish following published guidelines including, 2 independent forward, 2 independent blind backward translations, expert panel review by 7 members and field testing with 11 cognitive interviews (5 patients and 6 specialists) and final approval of the copyright holder. Consecutive cancer patients (n = 234) seen by the community palliative care services were recruited from Help Those with Cancer Society (KHYD); of those 82 were followed-up. The instrument was administered by personal interview. Confirmatory Factor Analysis was used to validate the factor structure of Turkish IPOS. Internal consistency reliability of the subscales was evaluated by Cronbach's alpha and Intraclass Correlation Coefficient respectively. Validity was assessed by calculating Pearson's correlation coefficient (r) between Turkish IPOS scores and Turkish version of EQ-5D-3L - a validated generic measure of health status developed by the EuroQol Group. RESULTS: Turkish IPOS is conceptually and semantically equivalent to the English version and linguistically valid. The CFA was inconclusive for the three factor structure due to low sample size, as the SRMR and CFI tests only approached the defined minimums warranting further investigation. There were low levels of missing values, and no ceiling or floor effects. The Physical (α = 0.91) and the Social and Quality of Care Issues (α = 0.75) sub-scales showed good internal consistencies, however Emotional sub-scale showed poor internal consistency (α = 0.64). The reliability of the Physical (ICC = 0.51, 0.45-0.56 95% CI) and Social Quality of Care Issues (ICC = 0.50, 0.42-0.57 95% CI) were moderate. Poor internal consistency (α =0.64) and reliability (ICC = 0.31, 0.24-0.39, 95% CI) was obtained for Emotional Subscale. Construct validity was evidenced through significant correlations in the predicted directions and strength with EQ-5D. Turkish IPOS showed higher needs and concerns in participants at more advanced stages than those at earlier stages of cancer. The standardized response mean (SRM) of - 0.94 suggested large internal responsiveness to clinical change. CONCLUSION: Turkish IPOS is a clear, relevant, acceptable measure and responsive to the needs and concerns of cancer patients, observing regional differences, it may have implications for use in other Turkish speaking communities. Future studies are needed to clarify the factor structure, assess its external responsiveness and to improve the properties of its Emotional subscale.

Psychometric properties of the adapted measles vaccine hesitancy scale in Sudan.

BACKGROUND: There is a need for reliable and validated tools to identify, classify, and quantify vaccine-hesitancy in low and middle-income countries, such as Sudan. We evaluated the psychometric properties of an adapted version of the measles vaccine hesitancy scale by assessing its reliability, convergent validity, and criterion validity in Sudan. The vaccine hesitancy scale (VHS) was originally developed by the WHO/SAGE Working Group of Vaccine Hesitancy. METHODS: A community-based survey among parents was conducted in February 2019 in Khartoum state. We conducted exploratory and confirmatory factor analysis to examine the structure of the adapted measles VHS (aMVHS). We computed Cronbach's alphas, correlations with other vaccine hesitancy measurements including the Parental Attitude towards Childhood Vaccination (PACV) and the Vaccine Confidence Index (VCI), and performed a Mann-Whitney U test for assessing the reliability and the convergent and criterion validity, respectively. Moreover, to examine whether the aMVHS can predict the child's vaccination status, the area under the curve (AUC) was estimated using receiver operator characteristic (ROC) curves. RESULTS: The questionnaire was completed by 500 parents. Most were women (87.2%) between the ages of 20 and 47 (M = 31.15, SD = 5.74). The factor analyses indicated that the aMVHS comprises of two factors (sub-scales): 'confidence' and 'complacency'. The aMVHS sub-scales correlated weakly to moderately with the PACV and VCI scales. The area under the curve was 0.499 at most (P >0.05) and the aMVHS score did hardly differ between actually vaccinated and non-vaccinated children. CONCLUSION: Our findings underscore that the aMVHS and its confidence and complacency sub-scales are reliable and have a moderately good convergent validity. However, the aMVHS has a limitation in predicting the concurrent child's vaccination status. More work is needed to revise and amend this aMVHS, particularly by additionally including the 'convenience' construct and by further evaluating its validity in other contexts.

Factor structure of the professional quality of life scale among direct support professionals: factorial validity and scale reliability.

BACKGROUND: Direct support professionals (DSPs) support people with intellectual and developmental disabilities in activities of daily living. DSPs may experience both contentment and struggles with their work. As agencies grapple with their recruitment and retention, understanding DSPs' holistic work experience is important. The Professional Quality of Life (ProQOL) scale assesses multiple domains of work experiences (i.e. compassion satisfaction, burnout and secondary traumatic stress). Despite extensive use across helping professions, the ProQOL is largely absent from DSP research. METHOD: This study examined the factor structure of the ProQOL with DSPs. Using secondary data from 495 DSPs, confirmatory factor analysis was conducted to determine if the original three-factor structure holds for this population. RESULTS: We confirmed the factorial validity of the ProQOL with the three-factor solution. In the validation process, some modifications were suggested to the model, which also improved the scale reliability. CONCLUSIONS: The current study provides initial evidence of the factorial validity of the ProQOL when used with DSPs, as well as recommendations for subsequent improvements and future research.

The Metacognitive Processes of Decentering Scale: Development and initial validation of trait and state versions.

The ability to decenter from internal experiences is important for mental health. Consequently, improving decentering is a common therapeutic target, particularly for mindfulness-based interventions. However, extant decentering measures are limited as they fail to directly assess all 3 metacognitive processes recently theorized to subserve decentering. We thus conducted 4 studies to develop and test the Metacognitive Processes of Decentering-Trait (MPoD-t) and State (MPoD-s) scales. Consistent with the metacognitive processes model, exploratory factor analysis (N = 355) and then bifactor exploratory structural equation modeling (N = 275) indicated the MPoD-t was composed of three independent yet interrelated lower-order factors, metaawareness, (dis)identification with internal experience, and (non)reactivity to internal experience, which subserved an emergent, higher-order, decentering factor. We next found evidence of the MPoD-t's convergent validity; as well as known-groups criterion validity, wherein mindfulness practitioners reported higher MPoD-t scores than nonpractitioners. Item response theory analyses were then used to identify a subset of 3 MPoD-t items for the MPoD-s. Finally, we found evidence that the MPoD-s was sensitive to changes in state decentering following a brief mindfulness induction relative to an active control condition; and that MPoD-s changes mediated the effect of mindfulness on levels of pain and related outcomes among a sample of preoperative surgery patients (N = 82). These studies indicate the trait and state versions of the MPoD may prove useful for the study of decentering and its constituent metacognitive processes. As such, the MPoD may help advance our understanding of how the metacognitive processes of decentering support mental health and well-being.

Using the CHIME Personal Recovery Framework to Evaluate the Validity of the MHRM-10 in Individuals with Psychosis.

The recovery movement has revealed that outcomes which focuses on just symptoms and functioning may not be holistic and that consumer-rated outcomes may contribute to a more holistic and person-centric care model. However, a brief and effective measure is required in clinical settings; hence, the aim of the current study is to evaluate the psychometric properties of the briefest personal recovery measure- Mental Health Recovery Measure-10 items, using the CHIME (Connectedness, Hope and optimism about the future, Identity, Meaning in life, Empowerment) personal recovery framework. 64 outpatients with schizophrenia or schizoaffective disorder were assessed at two time points, 2 weeks apart. Data collected included sociodemographic information, MHRM-10, Psychological factors related to the CHIME framework, in respective order: RYFF subscale positive relations with others; Herth Hope Index (HHI); Internalized Stigma of Mental Illness (ISMI) and RYFF subscale self-acceptance; World Health Organization Quality of Life- BRIEF (WHOQOL-BREF); Empowerment, and Clinical factors- symptoms as measured by Positive and Negative Syndrome Scale, functioning (PSP) and depressive symptoms (CDSS). MHRM-10 demonstrated convergent validity with CHIME personal recovery psychological factors (all ρ > 0.5). MHRM-10 had excellent internal consistency (Cronbach's alpha = 0.904) and adequate test-retest reliability (ρ = 0.742, p < 0.001). Initial factor structure analysis revealed a one factor structure. The MHRM-10 is a valid instrument for use and can serve as a tool to facilitate a more collaborative and person-centric model of care for individuals with psychosis.

The Role of Self-Connection in the Relationship between Mindfulness and Meaning: A Longitudinal Examination.

BACKGROUND: Researchers have rarely examined mindfulness and meaning in a way that informs the causality and directionality of this relationship. The current research examines this relationship across time, further validates the Self-Connection Scale (SCS), and examines the role of self-connection in both moderating and mediating this relationship. This allows for researchers and practitioners alike to utilise self-connection to help increase their own and others' well-being. METHODS: One hundred and fifty-four participants completed measures of mindfulness, self-connection, and meaning over 4 weeks. We also included various measures related to well-being to further examine the nomological network of the SCS. RESULTS: Multi-level models examined a total of 432 observations across 108 participants. Mindfulness predicted an increase in the presence of but not search for meaning. Self-connection partially mediated the effect on the presence of meaning and moderated the effect on the search for meaning. Furthermore, the SCS demonstrated good validity and reliability across time. CONCLUSIONS: Self-connection, as measured by the SCS, has an important role in positive psychology, and those with a deficit are likely to benefit the most from increased mindfulness. Together, this provides several implications for using mindfulness and self-connection research in personal and professional practice.

The assessment of spiritual well-being in cancer patients with advanced disease: which are its meaningful dimensions?

BACKGROUND: Spirituality is particularly important for patients suffering from life-threatening illness. Despite research showing the benefits of spiritual assessment and care for terminally ill patients, their spiritual needs are rarely addressed in clinical practice. This study examined the factor structure and reliability of the Functional Assessment of Chronic Illness Therapy-Spiritual (FACIT-Sp) in patients with advanced cancer. It also examined the clinical meaning and reference intervals of FACIT-Sp scores in cancer patients subgroups through a literature review. METHODS: A forward-backward translation procedure was adopted to develop the Italian version of the FACIT-Sp, which was administered to 150 terminally ill cancer patients. Exploratory factor analysis was used for construct validity, while Cronbach's α was used to assess the reliability of the scale. RESULTS: This study replicates previous findings indicating that the FACIT-Sp distinguish well between features of meaning, peace, and faith. In addition, the internal consistency of the FACIT-Sp was acceptable. The literature review also showed that terminal cancer patients have the lowest scores on the Faith and Meaning subscales, whereas cancer survivors have the highest scores on Faith. CONCLUSIONS: The Italian version of the FACIT-Sp has good construct validity and acceptable reliability. Therefore, it can be used as a tool to assess spiritual well-being in Italian terminally ill cancer patients. This study provides reference intervals of FACIT-Sp scores in newly diagnosed cancer patients, cancer survivors, and terminally ill cancer patients and further highlights the clinical meaning of such detailed assessment.

Development and content validation of the Burden of Documentation for Nurses and Midwives (BurDoNsaM) survey.

AIM: To develop a validated tool to measure nursing and midwifery documentation burden. BACKGROUND: While an important record of care, documentation can be burdensome for nurses and midwives and may remove them from direct patient care, resulting in decreased job satisfaction, associated with decreased patient satisfaction. The amount of documentation is increasing at a time where staff rationalisation results in decreasing numbers of clinicians at the bedside. No instrument is available to measure staff perceptions of the burden of clinical documentation. DESIGN: Survey development, followed by rwo rounds of content validation (April and May 2019). METHODS: Based on the literature a 28 item survey, with items in 6 subscales, representing key areas of documentation burden was developed. Item (I-CVI), subscale (S-CVI/Ave by subscale) and overall content validity indexes (S-CVI/Ave) were calculated following two review rounds by an expert panel of clinical and academic nurses and midwives. RESULTS: Level of agreement for the first iteration of the survey was low, with many items failing to reach the critical I-CVI threshold of 0.78. No subscale reached a S-CVI/Ave above 0.8 and the overall scale only achieved a S-CVI/Ave score of 0.67. Thirteen items were removed, seven were edited and five new items added, based on the expert panel feedback, substantially improving the content validity. All individual items achieved an I-CVI ≥0.78, the S-CVI/Ave was above 0.85 for all subscales and the total S-CVI/Ave was 0.94. CONCLUSION: The Burden of Documentation for Nurses and Midwives (BurDoNsaM) survey can be considered as content valid, according to the content validity analysis by an expert panel. IMPACT: The BurDoNsaM survey may be used by nurse leaders and researchers to measure the burden of documentation, providing the opportunity to review practice and implement strategies to decrease documentation burden, potentially improving patient satisfaction with the care received.

Development and Validation of the Thought Impact Scale: A Measure of Subconscious Connectedness.

The Thought Impact Scale (TIS) is a new questionnaire designed to measure the theorized psychological characteristic of subconscious connectedness, defined as the degree to which nonconscious mental functions spontaneously interact with, and are accessible to, conscious awareness in everyday life. A principal reason for developing the TIS was the expectation that subconscious connectedness influences hypnosis treatment responses and seeking of hypnosis treatment. Two studies involving 1,216 subjects were carried out to validate the questionnaire. The TIS exhibited high internal consistency (Cronbach's alpha of 0.93 and 0.95), good one-month test-retest reliability (r = 0.89), and convergent validity evidenced by substantial correlations with other measures hypothesized to partly assess the same construct: Absorption (r = 0.70), fantasy proneness (r = 0.54), dissociation (r = 0.50), and emotional empathy (r = 0.39). TIS scores were approximately normally distributed, higher in females than males, and declining with age. Exploratory factor analysis showed the TIS to be composed of a single dominant factor. High TIS scorers were 2.5 times as likely as low scorers to have undergone hypnosis treatment, 2.6 times as likely to report at least moderate benefit after hypnosis treatment, and 3.8 times as likely to consider themselves highly hypnotizable. High TIS scorers also more frequently reported being highly creative, art lovers, intuition-reliant, absentminded, spontaneous, novelty-seeking, and prone to form intense relationships. The TIS is a reliable and valid measure that is likely to be useful in clinical hypnosis practice and hypnosis research and for quantifying communication between conscious and nonconscious mental functions.

Spanish validation of the short-form of the Avoidance and Fusion Questionnaire (AFQ-Y8) with children and adolescents.

The Avoidance and Fusion Questionnaire for Youth-Short Form (AFQ-Y8) was designed to measure psychological inflexibility in children and adolescents. However, it has not yet been validated to the Spanish population. The present study examines the factorial structure, internal consistency, convergent and incremental validity, and measurement invariance between children and adolescents, male and female, and male and female across age of the AFQ-Y8 with 982 students from Spain (children = 459, adolescents = 523). The results confirmed, in both children and adolescents, a unifactorial structure of general psychological inflexibility. AFQ-Y8 was positively related to negative psychological health outcomes, and negatively related to positive psychological health outcomes and acceptance-related skills, such as mindfulness. In addition, psychological inflexibility showed incremental validity in the explanation of negative psychological health over mindfulness. Measurement invariance across age and gender groups was supported, suggesting that the scores in the AFQ-Y8 are comparable between children and adolescents, and between males and females. In conclusion, results show that the Spanish version of the AFQ-Y8 is a reliable and valid measure of psychological inflexibility in children and adolescents.

Validation of the Belief Into Action Scale (BIAC) in Portuguese Cancer Patients Receiving Chemotherapy.

Background: A large proportion of the world's population have religious beliefs, with 84.0% indicating an affiliation with a specific religious group. Few comprehensive measures to assess religious involvement currently exist in Portugal, particularly for the assessment of religiosity in cancer patients. Objective: To translate, adapt, and validate the 10-item Belief Into Action Scale (BIAC) in Portuguese cancer patients undergoing chemotherapy. Method: The methodological guidelines provided by Sousa and Rojjanasrirat were used to examine the psychometric properties of the BIAC. Results: The linguistic and conceptual equivalence of the scale was determined. The internal consistency was acceptable (Cronbach's α = .86). Varimax rotation with Kaiser normalization identified two factors made up of nine items. Conclusion: The European Portuguese version of the BIAC is a reliable and valid measure for assessing religiosity in cancer patients receiving chemotherapy to provide holistic care.

Validation of the Philadelphia Mindfulness Scale on experienced meditators and nonmeditators.

OBJECTIVE: The Philadelphia Mindfulness Scale's (PHLMS) psychometric properties, theoretical assumptions, convergent validity, and relationships to symptom, happiness and social desirability measures were investigated in novel samples. METHODS: Internet-recruited general public samples of experienced meditators (n = 67, 21 male, 46 female, average age 50) and nonmeditators (n = 61, 28 male, 32 female, and 1 transgender; average age 41.9) were used. RESULTS: Meditators scored higher than nonmeditators on both PHLMS Acceptance, t(126) = 2.77, p < .01, d = 0.49, and Awareness t(126) = 4.18, p < .01, d = 0.74. Higher PHLMS Acceptance subscale scores were associated with decreased scores on all symptom measures in nonmeditators, but only in select measures among meditators. Generally, PHLMS Awareness subscale scores were not related to symptoms. Awareness interacted with meditator status on outcome measures. CONCLUSIONS: PHLMS may be used in the general public and experienced meditator populations. Mindfulness facets become intercorrelated in experienced meditators.

Development of a Short Form of the Five Facet Mindfulness Questionnaire-Adolescents for Children and Adolescents.

The Five Facet Mindfulness Questionnaire (FFMQ) assesses several dimensions of mindfulness. The objective of this study was to develop a short version of the FFMQ for children and adolescents. The main sample consisted of 829 participants (51% boys; 10-18 years old). From this initial sample, 789 participants (49% boys) completed the FFMQ at a 6-month follow-up. A second independent sample (N = 418, 50% boys; 12-16 years old) was used to confirm the factor structure. Confirmatory factor analyses with the full version supported a structure composed of 5 correlated factors (1 per facet) plus 2 correlated method factors representing the method effect (positive and negative) of the items. From this model, the FFMQ-A-SF was derived, consisting of 25 items (5 per facet). The measure displayed adequate internal consistency, and invariance was confirmed over time and across different age groups. The analysis of the relationship between mindfulness facets and temperament and psychological problems provided additional evidence for the construct validity of the questionnaire. It is concluded that the FFMQ-A-SF presents acceptable validity and reliability in children and adolescents. However, the positive versus negative wording of the items could affect the responses of younger participants.

Psychometric properties and validation of the Swedish Five Facet Mindfulness Questionnaire in a clinical and non-clinical sample among meditators and non-meditators.

Over a period of 15 years several attempts to conceptualize mindfulness have been presented and revised, but there is still no clear or agreed-upon definition. The use of mindfulness-based interventions has increased in clinical and research settings the last couple of years, including in Sweden. As a clinician it is crucial to know if a treatment works through the theoretically postulated mechanisms of change. Mindfulness is a concept that is difficult to measure. The overall aim of the current project was to examine the psychometric properties of the Swedish version of the Five Facet Mindfulness Questionnaire (FFMQ_SWE) using three different studies. To test the construct validity of the FFMQ_SWE a hierarchal confirmatory factor analysis was performed in a meditating non-clinical sample, to examine if all the five facets would load on an overall mindfulness construct. Psychometric properties of the instrument were examined in a non-clinical and a clinical sample, and discriminative relationships with other variables were analysed. The convergent validity was examined by analysing the correlations between FFMQ_SWE and Hospital Anxiety and Depression Scale, Sense of Coherence and Difficulties in Emotion Regulation Scale. Test-retest reliability was tested by distributing FFMQ_SWE at two occasions. The hierarchal confirmatory factor analysis showed good fit in a population of meditators. The FFMQ_SWE showed good convergent validity and test-retest reliability in both clinical and non-clinical populations. In sum, the Swedish version of the FFMQ showed good psychometric properties and can be a useful instrument as an evaluation of treatment effects in both health care settings and research settings.

Do questionnaires reflect their purported cognitive functions?

Questionnaires are used widely across psychology and permit valuable insights into a person's thoughts and beliefs, which are difficult to derive from task performance measures alone. Given their importance and widespread use, it is vital that questionnaires map onto the cognitive functions they purport to reflect. However, where performance on naturalistic tasks such as imagination, autobiographical memory, future thinking and navigation is concerned, there is a dearth of knowledge about the relationships between task performance and questionnaire measures. Questionnaires are also typically designed to probe a specific aspect of cognition, when instead researchers sometimes want to obtain a broad profile of a participant. To the best of our knowledge, no questionnaire exists that asks simple single questions about a wide range of cognitive functions. To address these gaps in the literature, we recruited a large sample of participants (n=217), all of whom completed a battery of widely used questionnaires and performed naturalistic tasks involving imagination, autobiographical memory, future thinking and navigation. We also devised a questionnaire that comprised simple single questions about the cognitive functions of interest. There were four main findings. First, imagination and navigation questionnaires reflected performance on their related tasks. Second, memory questionnaires were associated with autobiographical memory vividness and not internal (episodic) details. Third, imagery questionnaires were more associated with autobiographical memory vividness and future thinking than the questionnaires purporting to reflect these functions. Finally, initial exploratory analyses suggested that a broad profile of information can be obtained efficiently using a small number of simple single questions, and these modelled task performance comparably to established questionnaires in young, healthy adults. Overall, while some questionnaires can act as proxies for behaviour, the relationships between memory and future thinking tasks and questionnaires are more complex and require further elucidation.

Cross-validation of the Care Dependency Scale in intensive care unit (ICU-CDS).

OBJECTIVES: The Care Dependency Scale is a theory-based, comprehensive tool widely used in low-intensity care settings to evaluate patients' dependency. This study aimed to test the psychometric properties of the Care Dependency Scale in intensive care units. RESEARCH METHODOLOGY/DESIGN: A multicentre cross-sectional validation study was conducted. Exploratory factor analysis and confirmatory factor analysis were performed using a Maximum Likelihood robust estimator with Geomin oblique rotation. SETTING: Adult patients admitted to intensive care units of four Italian hospitals. RESULTS: The sample included 453 patients (mean age = 68 years, 62% male). The exploratory factor analysis, conducted on a subsample of 227 patients, revealed a two-factor structure (Physical care dependency and Psychosocial care dependency) with good fit indexes. The confirmatory factor analysis was conducted on another subsample of 226 patients and a second-order factor was specified. The model tested yielded adequate fit indexes. Concurrent and known-groups validity, and reliability, were also adequate. CONCLUSION: The Care Dependency Scale is a multidimensional, valid and reliable tool able to assess the care dependency of critically ill patients. It can help to distinguish between physical and psychosocial needs and to create a base for patient-customised and holistic care.
