A Psychometric Evaluation of the Threadgold Communication Tool for Persons with Dementia

The use of digital touch screen technology to deliver reminiscence therapy among people with dementia in Jordanian care homes: a mixed-method feasibility study

BACKGROUND

Using technology to deliver psychosocial interventions such as reminiscence therapy (RT) to people with dementia may improve their mental health. Yet, establishing the feasibility of digital interventions in low- to middle-income countries is still in the early stages. This study aimed to: (i) determine the feasibility of using digital touch screen technology to deliver RT among people with dementia living in Jordanian care homes; and (ii) compare study outcomes pre- and post-reminiscence sessions to investigate whether specific outcomes are sensitive to change and explore the acceptability and experiences of the intervention.

METHODS

A pragmatic mixed-method study design was implemented. Sixty residents with dementia were recruited from two Jordanian care homes (Site 1: n = 35; Site 2: n = 10). A process evaluation was conducted alongside a single-group pre-post-intervention study. The intervention involved 10 supported RT sessions of up to 1 h each, delivered over 5 weeks. Feasibility was determined by assessing the rate of recruitment, adherence, retention, data completion, implementation fidelity, and adverse events. Qualitative semi-structured interview questions were used to explore experience and acceptability, and data were thematically analysed.

RESULTS

Response rate was 100%; loss to follow up at post-intervention was 25%. Median session attendance for those who received the intervention was 80%. No serious adverse events were reported. A positive, statistically significant and clinically relevant difference was found in all outcome measures before and after reminiscence sessions. Qualitative findings suggest that digital RT intervention is generally well accepted by people with dementia who reported positive changes, including enhanced communication and cognitive abilities.

CONCLUSION

Using digital touch screen technology to deliver RT is feasible and acceptable among people with dementia in Jordanian care homes. Digital RT intervention is a promising approach to improving mental health and communication for people living with dementia.

Clinimetric Evaluation of the Experienced Communication in Dementia Questionnaire

BACKGROUND AND OBJECTIVES

Tools to measure self-perceived communication between persons with early-stage dementia and their caregivers are lacking. Therefore, we developed a questionnaire for Experienced Communication in Dementia (ECD) with a patient version (ECD-P) and a caregiver version (ECD-C), which contains items on (a) caregiver competence, (b) social communication, (c) communication difficulties, and (d) experienced emotions. This article describes the feasibility and clinimetric evaluation of this instrument.

RESEARCH DESIGN AND METHODS

A prospective observational cohort study was conducted with 57 dyads (community-dwelling person with dementia and primary caregiver). ECD-P, ECD-C, and measures on quality of life, caregiver burden, cognitive functioning, physical functioning, and functional independence were administered. After 2 weeks, the dyads filled out the ECD again. Feasibility (completion time and missing values per item), internal consistency (Cronbach's α), test-retest reliability (intraclass correlation coefficients [ICCs]), and construct validity (hypotheses testing with Spearman's r) were evaluated.

RESULTS

Mean completion time was 10 min per questionnaire. ICCs for test-retest reliability ranged from 0.67 to 0.78, except for ECD-P2 (ICC = 0.31). Internal consistency ranged from α = 0.75 to 0.82 for ECD-P1 and all parts of ECD-C, except for ECD-P2 (α = 0.66). Correlation coefficients for convergent validity ranged from r = 0.31 to 0.69 and correlation coefficients for divergent validity were r < 0.20 and statistically insignificant.

DISCUSSION AND IMPLICATIONS

Pending future research, the ECD, except part ECD-P2, seems to be a promising tool to measure experienced communication between persons with early-stage dementia and their caregivers.

Assessing cognitive communication skills in dementia: a scoping review

BACKGROUND

Cognitive communication difficulties are a characteristic feature of dementia. These deficits have negative effects on all aspects of daily life. Yet, there are few options for standardized assessment of cognitive communication skills in people with dementia.

AIMS

To review published cognitive-communication assessments to determine what psychometrically sound assessments exist that are applicable to all people with dementia.

METHODS & PROCEDURES

A scoping review of the literature was conducted using an established scoping review model. Cognitive-communication assessments validated in English with people with dementia were sought. A comprehensive search of eight relevant electronic databases was undertaken. Two reviewers independently analysed and assessed the psychometric quality of instruments that met inclusion criteria.

OUTCOMES & RESULTS

Four cognitive-communication assessments were included in the review. Although psychometrically sound, none was suitable for administration at all stages of dementia. Only one was validated for different dementia types. None included subtests for evaluation of conversation ability, and none involved the evaluation of communication partners' communication.

CONCLUSIONS & IMPLICATIONS

There are limited options for standardized communication assessment for individuals with dementia and their communication partners. Directions for the development of new measures are provided to facilitate research and improve clinical practice.

Impact of the Sonas Programme on Communication over a Period of 24 Weeks in People with Moderate-to-Severe Dementia

Objectives

The primary aim was to examine how communication abilities changed over time among nursing home residents with moderate-to-severe dementia who were attending the Sonas programme and to explore whether changes in communication abilities were related to cognitive ability.

Method

A longitudinal secondary descriptive study method was employed, where 56 people with moderate-to-severe dementia attended a 45-min Sonas group session twice a week for 24 weeks. The Threadgold Communication Tool (TCT) was completed every 4 weeks.

Results

The impact of the Sonas programme on communication showed a significant non-linear trend in the TCT, with an increase in communication abilities during the first 16 weeks, regardless of the level of the residents' cognitive abilities. Thereafter it levelled out. No interaction was found between time and the frequency of attendances at Sonas sessions. Both verbal and non-verbal communication increased from the baseline, with non-verbal communication increasing quickly and verbal communication increasing marginally.

Conclusion

Communication abilities increased with the time of the intervention, but the peak was achieved after 16 weeks, after which the effect levelled out. This suggest that the Sonas programme should be used for a period of at least 16 weeks before evaluating its effect.

Preliminary Psychometric Properties of the Verbal and Nonverbal Interaction Scale: An Observational Measure for Communication in Persons with Dementia

Little attention has been given to sociable/unsociable communication in persons with dementia despite the importance of these behaviors in maintaining engagement in marital relationships. An observational measure of verbal and nonverbal communication in persons with dementia (Verbal and Nonverbal Interaction Scale-CR) who were engaged in conversations with spouses was tested for reliability and validity. Married persons with dementia were video-recorded at home conversing with spouses over 10 weeks (N = 118 recordings). Reliability [inter-coder (.92), test-retest (r =.61-.77), internal consistency (α =.65 -.79)] were adequate. Following an intervention, the Verbal and Nonverbal Interaction Scale-CR predicted improved communication over 10 weeks. The ratio of sociable to unsociable communication improved by 4.46 points per session [β = 4.46, t(10) = 1.96, p =.039]. VNVIS-CR is recommended to describe sociable and unsociable communication in persons with dementia as they engage in conversations with spouses.

Psychometric evaluation of the Holden Communication Scale (HCS) for persons with dementia

OBJECTIVE

To investigate the psychometric properties of the Holden Communication Scale (HCS) and the association between scores on HCS and cognitive function among persons with dementia.

METHOD

Internal consistency was assessed by the Cronbach's α coefficient and inter-item correlations. Test-retest was carried out to test the instrument's stability. An exploratory factor analysis with the principal components extraction method and oblimin rotation was performed to evaluate construct validity. Pearson's correlation coefficients were calculated to explore associations between the scores on the HCS and cognitive function.

RESULTS

A total of 128 persons with moderate-to-severe cognitive impairment (mean Mini-Mental State Examination (MMSE) score 8.9 (SD 7.0)) participated. The mean age was 85.2 (SD 7.2) and 101 of the participants were women. The Cronbach's α of the HCS was 0.94 and test-retest reliability was r=0.71. The corrected item-total correlation ranged from 0.63 to 0.79 and factor analysis showed a 1-factor structure of the HCS, which explained 63% of the variance. However, a forced 3-factor structure explained 76% of the variance. The correlation between cognitive function as measured by the MMSE and ability to communicate as measured with HCS was found to be moderate for those with an MMSE score of 0-10 (-0.61) and low for persons with an MMSE score of 11-20 (-0.06).

CONCLUSIONS

The HCS is a reliable and valid scale for assessing communication ability in persons with moderate and severe cognitive impairment, and might have a 1-factor or 3-factor structure.
