Brief Summary

This study is a 2-arm, parallel, randomised controlled feasibility trial of a brief video intervention designed to induce positive affect (mood) in older adults in primary care settings prior to the receipt of influenza vaccination. Participants will be randomised into two conditions: experimental and active control. In the experimental condition, participants will view the approximately 15 minute long intervention video immediately prior to vaccination. In the active control condition, participants will view a matched video that is designed to be mood neutral. Pre-and-post positive affect levels will be assessed by self-report questionnaires. Immune response to the intervention and vaccination responses will be assessed in saliva and serum samples respectively. The objectives of the study are to assess the impact of the intervention on mood, immune function, and antibody response to influenza vaccination in older adults. This feasibility trial will also allow data collection on exploring recruitment, attrition, intervention engagement, and practicality of collecting clinical data available through electronic records to inform the design of a future definitive trial.

Outcome Measures

Primary Outcomes (1)

  • Mood Outcome Scores [Multiple]

    Affective Slider (Betella \& Verschure, 2016), consists of two single item visual analogue scales. Scores for each are presented as a value from 0 to 100 with higher scores indicating greater pleasure (VAS-Valence) and arousal (VAS-Arousal). Positive and Negative Affect Schedule (Watson et al., 1988). Positive and negative affect subscales were created by summing the scores of positive and negative adjectives respectively. For each sub scale, minimum score = 10, maximum score = 50 with higher scores indicating greater positive and negative affect respectively. Pictorial scale of positive affect (unvalidated, internally developed). Participants completed a single-item photo-based measure of positive affect tailored for older adults. Participants were presented with six groups of images depicting varying degrees of positive affect, and indicate which best reflected how they felt at that moment. Minumum score 1, maximum score 6, higher scores indicate greater positive affect.

    Baseline, Immediately Post Intervention (i.e, 15 minutes post-baseline).

Secondary Outcomes (5)

  • Attrition

    4 weeks (post-vaccination), 16 Weeks (post-vaccination)

  • Secretory IgA Response

    Baseline, Immediately Post Intervention (i.e, 15 minutes post-baseline).

  • Vaccine Specific IgG Response

    4 weeks (post-vaccination), 16 Weeks (post-vaccination)

  • Health Care Utilization

    Baseline to 6 months post-vaccination

Study Arms (2)

Experimental

EXPERIMENTAL

Participants in the experimental condition will view a video designed to induce positive affect. This includes 3 short comedy clips (fork handles sketch, the two Ronnie's; A room with a view - faulty towers; Tim Vine Live stand-up extract), uplifting music (Jailhouse Rock - Elvis Presley; Happy Together - The Turtles), jokes and positive imagery. The content of the intervention has been informed by patient and public involvement, focus groups with older adults, and pilot testing.

Other: Positive Affect InterventionBiological: Northern Hemisphere Influenza Vaccine 2017/18 (Delivered as part of Standard Care)

Active Control

ACTIVE COMPARATOR

Participants in the control condition will view a video of matched length to the experimental condition video, but not designed to induce mood change. This includes short documentary clips (a pride in pencils; model railways, lecture extract on hydration), neutral music and images.
