Two hundred and forty (257) studies met the eligibility criteria following the deletion of 478 duplicates from the 735 studies identified at the title screening stage (Fig. 1).
Subsequently, 182 and 52 studies were excluded following abstract and full text screenings respectively. Reasons for exclusion were that 18 studies did not report on older adults only (6, 24, 43–58), 13 studies did not report on NVC (14, 59–70), 09 studies did not report on nurses and student nurses only (4, 71–78), and five studies did not report on nurses communicating with older adults (79–83). Additionally, six studies reported on older adults with communication impairment and/or mental illness (16, 84–88). The flow diagram (Fig. 1) following the PRISMA guidelines presents the selection process and all results and the final inclusion of 22 studies for data extraction.

Timeline (dates) for research
The earliest identified study meeting our eligibility criteria was published in 2000 (89). A growth in NVC between nurses and older adults with no communication impairment or mental illness research occurred for the next 10 years (n = 13). There were two studies in 2001 (90, 91), and four in 2009 (92–95). Between 2010 and 2019, eight studies relevant to the topic were retrieved (9, 22, 96–101).
Location (country) of research
Evidence on NVC between nurses and older adults with no communication impairment or mental illness have largely been reported in the USA (22, 89, 91, 93, 94, 99, 101–104) (45.5%; n = 10). Research from American countries represented 63.6% of all studies which includes two Canadian studies (100, 105), and two in Brazil (96, 97). Research was also conducted in European countries such as Germany (90), Ireland (9), Sweden (98), and the Balkans (95). Only one study was conducted in Korea (106) and there was no mention of a study conducted in an African country. Two studies were not primary studies but were written by authors from the UK (8) and Ireland (9).
Study designs
Diverse research methods were employed within the 22 included studies. The majority (n = 11, 50%) were qualitative studies using individual interviews, focus groups, observations, participant logs, and video recordings. There were also three quantitative studies with one randomized controlled trial, as well as two mixed methods studies. The other three studies were a review (101) and two continuous professional development contents (8, 9).
Quality of evidence
Of the 22 included studies, 16 underwent methodological quality assessment using the MMAT version 2018 (38). The remaining six (8, 9, 89, 90, 101, 102) were excluded for quality appraisal because they were not primary studies. The 16 studies which underwent methodological quality assessment showed high methodological quality appraisal and scored between 80 and 100%. Of these, 15 studies (22, 91–100, 103–105, 107) scored 100%, and one (106) scored 80%.
Study results
Two outcomes were reported in the studies: the nonverbal cues used by nurses, and the older adults’ interpretation of these cues.
Nurses’ NVC cues
Of the 22 included studies, 20 reported on nurses’ NVC cues including: haptics, kinesics, proxemics, vocalics, active listening, artefacts, and chronemics. There was no mention of physical appearance nor silences in all the included studies.
Haptics
Haptics were reported in 16 studies where nurses shook hands with older adults, held their hands, stroked their hands or touched their hands. Nurses also kissed older adults, hugged them or gave them a pat on the shoulder.
In a study aiming at examining the special nature of communication between residents and staff in a Japanese elderly care institution, haptics were referred to as a handshake given by a staff against one older adults will (92). This type of touch was used in a joking atmosphere in Japan where handshakes are uncommon but was forced on the older adult who did not appreciate it. In another study conducted on types and examples of nurse aide-initiated communication with long-term care residents during mealtime assistance, haptics referred to a handshake when staff praised the older adults for eating all their food or to a touch on the arm for attention getting (104). Stroking older adults’ hands were reported to be a means of conveying attention when exploring the nature of communication between care staff and residents who did not share the same languages and ethno-cultural backgrounds (100).
Hugs were mentioned as a deliberate communication strategy used by a nurse practitioner to meet the unique needs of older adults in a study aimed at describing communication between nurse practitioners and older adults (103). Hugs were also mentioned as a strategy to establish rapport and prevent communication breakdowns between nurses and older adults (100). The nurses admitted that they consciously used NVC cues that are specific to each client. Additionally, a pat on the shoulder was mentioned as a caring gesture in a study aiming at characterizing the meaning of and experiences with individualized care from the perspectives of both nursing aides and nursing-home residents (99).
Touch had several connotations in a study aimed at exploring the nature of communication between care staff and residents with different languages and ethno-cultural backgrounds. Rubbing under the chin was used by the staff to stimulate sleepy older adults, holding his head back was used to appease a negative response from the older adult, and stroking the hand was used to convey affection (100).
Kinesics
Kinesics was reported in 13 studies. Pointing and thumbs up, as movements of the hands, were used by student nurses to communicate nonverbally when words were in short supply in a study aimed at demonstrating and discussing how personal competence can be developed by nursing students through international clinical practice (95). Pointing was also reported in a study describing how nurses communicate with older adults and their relatives in a department of medicine for older adults in western Sweden. Pointing was used by nurses to communicate with a learning perspective (98).
Kinesics also referred to movements of the head, which included facial expressions, movements of the eyes, and head nods. In a study aimed at ascertaining how student nurses communicate with older adults, facial expressions and eye contact were described as components of effective communication with older adults (107). Facial expressions such as a smile and laugher were reported in a study where staff occasionally engaged in smiling with older adults to both quickly and amicably resolve disagreements over their respective actions. Smiles were then seen as enhancers of the communication between nurses and older adults (100). Smile was also seen as a way to convey the message (95) or to initiate communication with older adults (104). Furthermore, smiles were used by nurses in an attempt to create a positive atmosphere during the meeting with older adults (98).
Student nurses described head nodding as a means to convey their message nonverbally when communicating with older adults (95). Nodding was also used to convey communicative intent nonverbally, and to indicate acceptance or rejection of staff’s actions (100), and to address or to praise the older adults (104). Additionally, nodding was used by nurses to show that they had understood what older adults and their relatives had said, in a study aiming at describing how nurses communicate with older adults and their relatives (98).
Eye gaze was seen as nurses’ willingness to be engaged in conversation in a review on evidence-based strategies for effective communication with older adults across long-term care settings (101). Eye gaze was also used to get older adults’ attention or as means to both connect relationally and instrumentally with the older adults (100). Additionally, eye gazing was used to get older adults’ attention, when the nature of communication between care staff and residents with different language and ethno-cultural backgrounds was explored (100). Eye contact was also suggested as an advice to effectively communicate with older adults (8) or a means of improving communication skills with them (90).
Movements of the body included leaning over older adults to assess their progress (90) or to check on them, in a study conducted on types and examples of nurse aide-initiated communication with long-term care residents during mealtime assistance (104). Additionally, leaning forward was a means to indicate the nurses’ eagerness and readiness to listen to the older adults’ stories, in a study providing pointers to help clinicians listen to the needs and concerns of older adults (102).
Proxemics
Proxemics, defined as the social meaning of space and interactive field, which determines how relationships occur [115] were reported in 10 studies, and included physical proximity and physical distance. Speaking far away was mentioned as a nurse-related communication barrier perceived both older adults and nurses while determining and comparing the communication barriers perceived by older adults and nurses caring for them (106). Additionally, nurses remained standing while using a medical voice to communicate with older adults, in a study describing communication with nurses and older adults in Sweden (98).
Sitting next to older adults was part of the playful gestures nurses engaged in, in a study which explored the nature of communication between care staff and residents with different languages and ethno-cultural backgrounds (100). Likewise, sitting at the older adult’s side to hold her hand was mentioned in a reflection on the nurse’s interaction (89), and sitting face to face was suggested to indicate the presence of the older adult and the readiness to listen while providing pointers to help clinicians listen to the needs and concerns of older adults (102). In a reflection on active listening, physical proximity was described as an enhancer to the ability to listen and a sign of interest in the older adults (90).
To create conditions for planning a good home return, a nurse sat down on her knee in front of the older adult (98). Kneeling down was also used by nurses to make eye contact with older adults’, in a study describing communication between nurses and older adults (98). Nurses positioning themselves at the same level as older adults was described as a strategy to support nurses’ communication with older adults when promoting effective communication in practice (9).
Vocalics
Vocalics were reported in nine studies where they described different aspects of the voice. A military tone with endearment was used to address an older adult, in a study examining the special nature of communication between residents and staff in a Japanese elderly care institution (92). The old adult did not appreciate the tone of the staff member, though she was joking. Conversely, though to no avail, a soft tone was used by a nurse to encourage an older adult to eat her food (104).
Speaking too quickly and in a demeaning tone were reported as barriers to effective communication when exploring the skills that are required for effective communication with older adults (8). Likewise, speaking too loudly and speaking too fast were nurse-related communication barriers as perceived by nurses and older adults (106). Speaking faster and with a monotonous tone was reported when nurses used a medical voice to communicate with older adults. When they used a power voice, they spoke louder and with great emphasis on selected words (98).
Conversely, speaking calmly contributed to create mutual trust in the student nurse-older adult relationships in a study demonstrating that communication and empathy can be developed by student nurses through clinical practice (95). Speaking slower was a means for student nurses to be understood by older adults in a study to ascertain communication between student nurses and older adults (107). Additionally, a friendly tone was used by nurses to increase the knowledge of older adults when communicating with them in Sweden (98).
Listening
Listening was reported in seven studies. In one instance, listening was reported as a means to help nurses assess older adults’ physical condition more effectively (90). Active listening coupled with compassionate listening was one of the strategies to support nurses’ communication with older adults when promoting effective communication in practice (9). Active listening also was identified by nurse practitioners as one of the specific communication strategies proven to be helpful with older adults in a description of communication between nurse practitioners and older adults (103). To listen empathetically and nonjudgmentally while being aware of the body language the older adults used provided pointers to help nurses listen to the needs and concerns of their clients (102).
Actively listening to older adults’ verbal and NVC behaviors was seen as leading to individualized care in a study characterizing the meaning of and experiences with individualized care from the perspectives of both nursing aides and nursing-home residents (99). In the same study, nursing aids reported that they indicated to the older adults that they were showing them respect by actively listening to them. For nursing students, active listening in relation to non-verbal communication was seen as an empathic response and an open- minded attitude (95).
Artefacts
Artefacts were reported in five of the 22 included studies. Artefacts included notes and hands-on learning tools seen as strategies to improve communication skills in a speech on active listening (90). They were also referred to as flyers, pamphlets, written instructions, books and education files in a study aimed at describing communication between nurse practitioners and older adults (103). Artefacts were communication supports and aids that can support nurses’ communication with older adults (9).
When promoting effective communication in practice, it was advised that nurses should be mindful of the physical environment that can affect interactions between them and older adults (9). For instance, the nurse should avoid speaking whilst wearing a mask, as it is considered as an impediment to effective communication (106). Nurses closed the door on an older adult when using a pedagogical voice in Sweden (98). It avoided any disturbance of the communication exchange.
Chronemics
Chronemics were reported in three studies with nurses’ NVC other cues. In a study aiming at identifying the communication behaviors and strategies used by socially skilled geriatric nurse aides working with residents in long term care facilities (22), spending time with older adults was described by the nurses as giving a positive regard to the older adults. Giving a positive regard meant being respectful, acknowledging and showing interest and approval to the older adults. In her reflection on active listening, Bush (90) mentioned spending more time with older patients as a means to promote feelings of acceptance. Yet, she acknowledged exercising patience as the most challenging part of the communication process. Likewise, Kaakinen (103) found that time positively affected nurse practitioners-older adults relationship when describing communication between nurse practitioners and older adults.
Old adults’ perceptions of nurses’ NVC cues
Six studies reported on the older adults’ perceptions of nurses’ NVC cues. The perceptions were either positive or negative.
Positive perceptions
Positive perceptions of nurses’ NVC cues were reported in three studies. In the first study, comfort touch from nurses was shown to improve the perceptions of self-esteem, well-being, social processes, health status, life satisfaction, self-actualization, and faith or belief (91). In a study exploring the experience of being listened to for older adults living in long-term care facilities, results showed that older adults expressed their satisfaction, gratification, and unburdening that came with being listened to by nurses (105). They also described their relationships with the nurses who listened to them as being close like friends or family (105). A pat on the shoulder was perceived as a sign of respect and care by the older adults in a study aimed at characterizing the meaning of and experiences with individualized care from the perspectives of both nursing aides and nursing-home residents (99).
Negative perceptions
Negative perceptions of nurses’ NVC cues were reported in three studies. In a study aimed at exploring how communication affects issues relating to residents maintaining cognitive and physical functioning in order to remain in the residence, vocalics were perceived by the nurses as rudeness, disinterest, “infantilisation” and “adultification” (94). In a study with the aim to determine and compare the communication barriers perceived by older adults and nurses caring for them, speaking far away, without eye contact, wearing a mask and too loud was perceived as being unfriendly, working without a sincere attitude, and showing no respect (106). In a review of evidence-based strategies for effective communication with older adults across long-term care settings, touching their buttocks or looming over them were perceived by old adults as dominance, while glancing at their watch or down the hall was perceived as a sign of disinterest (101).
