INTRODUCTION

The word “humor” has received many meanings throughout history. However, one of the more recent definitions refers to it as an emotional state, a state of humor that may be more or less stable, and also as an expression of feelings that can promote well-being in a person⁽¹^-³⁾.

The Association for Applied and Therapeutic Humor (AATH) defines “Therapeutic humor is any intervention that promotes health and wellness by stimulating a playful discovery, expression or appreciation of the absurdity or incongruity of life’s situations”⁽⁴⁾.

In Nursing Intervention Classification (NIC) this intervention is defined as the one that allows nurses to help the person to perceive, appreciate and express what is funny, entertaining or humorous, to establish relationships, relieve tension, release anger and facilitating learning or dealing with painful feelings, with the intention of promoting and maintaining health⁽⁵⁾.

Humor and laughter are intertwined, mutually influenced, yet they are not synonyms. Humor is an emotional response and can be translated by joy and laughter. It is a behavioral manifestation. These are influenced by a context or situation; however, they cannot be discussed separately⁽¹^-³⁾.

Studies carried out in the field of humor as a nursing intervention have demonstrated that it is beneficial for people’s health and well-being⁽¹^-³^,⁶^-⁷⁾.

Given its importance, it has been integrated into nursing practice and classified nursing languages, as an intervention in NIC⁽⁵⁾ and as a resource and intervention in the International Classification for Nursing Practice (ICNP)⁽⁸⁾.

However, in care, nurses do not value it⁽³^,⁷^,⁹⁾, as they are afraid of being unprofessional, so it is not systematized in the planning and provision of care⁽³^,⁷⁾.

The benefits of humor in people’s health and life are as follows: it promotes well-being; helps deal with difficult and unpleasant situations; brings people together by leveling their roles; helps to share feelings; enables hope; promotes relaxation; reduces tension, stress and discomfort and, increases tolerance to pain and strengthens the immune system by increasing the activity of Natural Killer cells and increasing immunoglobulin levels⁽¹^,³^,⁹^-¹⁰⁾.

OBJECTIVES

To describe the factors influencing the use of humor in nursing care and its applicability; and,
To identify the benefits of humor intervention in nursing care.

METHODS

Ethical aspects

Although this study did not involve people directly, ethical procedures were guaranteed.

Design, study location and period

We used the scoping review methodology. It is defined as a technique to ‘map’ relevant literature in the field of interest. It consists of five steps: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarizing and reporting results⁽¹¹⁾.

The electronic research was carried out between May and June of 2018 using the platform EBSCO Host^® (CINAHL Complete e MEDLINE Complete) and Biblioteca Virtual de Saúde (BVS), complemented in Google Scholar and university repositories.

Study protocol

The starting question was defined from the framework - Patient (P), Concept (C_[1]) and Context (C_[2])⁽¹²⁾. In this sense, the research question was as following: what knowledge is produced regarding the integration of the humor intervention (C_[1]) in the interaction (C_[2]) nurse-person in a situation of disease (P)?

Two Boolean equations were used: [(Humor therapy) OR (Humor)] AND (review) AND (Nursing) AND (Wit and Humor as Topic) AND (Nursing). The descriptors were validated on platform of Health Science Descriptors (DeCS).

The research was conducted independently by two investigators from the research team, and the selection of the studies followed the same method, with the sequence suggested by international guidelines⁽¹³⁾. The results were obtained in a phased manner, from reading the title to reading the full text.

Samples, inclusion and exclusion criteria

Full text articles published in the last 10 years, in Portuguese, English, French and Spanish, that addressed the use of humor in nursing, influence factors, precautions and benefits of this intervention in the health of adults in the process of illness, were included.

Analysis of the Result

After the selection of articles, they were analyzed, and information was gathered about author(s), year of publication, study location, population (care recipient group), aims of the study, methodology and important results.

The level of evidence was classified according to the Registered Nurses’ Association of Ontario’s (RNAO) guidelines: Ia - Evidence obtained from meta-analysis or systematic review of randomized controlled studies Ib - Evidence obtained from at least one randomized controlled trial IIa - Evidence obtained from at least one well-designed controlled study without randomization IIb - Evidence obtained from at least one other type of well-designed quasi-experimental study III - Evidence obtained from a well-designed non-experimental descriptive study, such as comparative study, case; IV - Evidence obtained from reports of expert committees or opinions and / or clinical experiences of respected authorities⁽¹⁴⁾.

The identification, selection, eligibility, inclusion of studies and summary chart for each article in order to systematize the relevant information was conducted independently by two investigators.

RESULTS

A total of 465 articles were identified. After reading the title, abstract and complete article, 17 articles that fulfilled the inclusion criteria were selected for final revision (Figure 1)⁽²^-³^,⁶^-⁷^,⁹^-¹⁰^,¹⁵^-²⁵⁾.

Characteristics of studies analyzing humor intervention in nursing

These articles were published as follows: two in 2008⁽¹⁹^,²⁴⁾, two in 2013⁽⁶^,¹⁸⁾, five in 2014⁽⁹^-¹⁰^,¹⁶^-¹⁷^,²³⁾, two in 2015⁽²^,¹⁵⁾, four in 2016⁽³^,²⁰^-²²⁾ and two in 2018⁽⁷^,²⁵⁾.

On what concerns country of origin, they were from Australia⁽⁹^,¹⁵^,²³⁾, United States of America (USA)⁽¹⁷^,¹⁹⁾, Spain⁽²⁵⁾, United Kingdom (UK)⁽¹⁰^,¹⁶^,¹⁸^,²⁰^,²⁴⁾ and Portugal⁽²^-³^,⁶^-⁷^,²¹^-²²⁾.

The articles present the definition of humor in nursing⁽²^-³^,⁶^-⁷^,²¹^-²²⁾ and its use in several contexts⁽³^,⁶^-⁷^,⁹^-¹⁰^,¹⁵^,²⁰^,²⁴⁾, or in a specific context such as the perioperative period⁽¹⁹⁾, in people with dementia⁽¹⁷⁾, in palliative care⁽²⁵⁾, in people with cancer⁽¹⁶^,¹⁸⁾, in the context of orthopedics⁽²^,²²⁾, and in people undergoing hemodialysis⁽²¹^,²³⁾.

They describe the use and function of humor as a nursing intervention⁽³^,⁷^,⁹^,¹⁵^-¹⁶^,¹⁹^,²¹^-²⁴⁾, a communication⁽³^,⁷^,⁹⁾ and relation tool⁽³^,⁷^,⁹^-¹⁰⁾, actors that influence its use⁽²^-³^,⁷^,¹⁵^,²⁰^-²²^,²⁵⁾ and some barriers⁽³^,⁷^,²⁰⁾, the activities of humor intervention in the interaction with the person in the process of disease and its benefits⁽³^,⁶^-⁷^,⁹^-¹⁰^,¹⁶^,¹⁸^-¹⁹^,²¹^-²³^,²⁵⁾, as well as, the limitations and precautions with this intervention⁽³^,⁷^,¹⁷^,²⁰^,²²^,²⁴^-²⁵⁾.

DISCUSSION

The discussion was organized according to the categories defined after reading the selected articles, namely: definition; use and function of humor as a nursing intervention; nursing-patient communication and improvement tool; factors influencing the use of humor; activities of the humor intervention; benefits of humor in the context of health care and; limitations and precautions of humor intervention.

Definition

The humor concept in the treatment of cancer in adults⁽¹⁸⁾ is a subjective emotional response, resulting from the recognition and expression of incongruities of a comic, absurd, impulsive, observational or action situation. It fosters feelings of proximity or union when shared in a relationship of trust between the person in situation of illness and nurse, being able to be used in situations of stress, as, in the care of the person with cancer. This definition fits into the definition of NIC⁽⁵⁾ and AATH⁽⁴⁾ in which they humor is defined as an emotional response resulting from appreciation, recognition of incongruity, comprehension, and expression of what is funny, amusing, or comical⁽²^-³^,²⁵⁾. Together with people with cognitive impairment emerging themes of humor include nonsense, sarcasm and comments on the difficulties of dementia. Laughter was identified in moments with and without humor⁽¹⁷⁾.

Use and function of Humor as a nursing intervention

In the oncology context, two studies in the UK try to show how humor is used in people with cancer. One study explains how men with a diagnosis of penile cancer use humor in relation to their diagnosis and treatment and it is noticed that their use allows them to dedramatize diagnosis and treatment and improves the therapeutic relationship with healthcare professionals⁽¹⁶⁾. In this context nurses should use humor to build the therapeutic relationship but should avoid jokes about the sexual or urinary functioning of the person with penile cancer.

In a study about the influence that laughter therapy and humor therapy have on people undergoing hemodialysis, it has been confirmed that the use of these therapies in the form of humorous videos, stories, clowns and laughter yoga have positive results in depressive states, anxiety, pain relief, immunity, fatigue, sleep quality, and other physical aspects related to respiration and blood glucose⁽²³⁾.

The use of humor in the context of care improves the experience of hospitalized patients⁽⁷^,²⁵⁾, contributing to their satisfaction, increased participation and adherence to the therapeutic regimen. Humor can play an important and even decisive role in the promotion of presence (present moment) that facilitates learning.

Nursing-patient communication and improvement tool

It is understood that both humor and laughter play a role in creating a safe social environment⁽¹⁷⁾. Another study explores the experience of four nurses using humor in their practice. It tries to understand whether there are gender differences in its use and if the humor intervention influences nurse / patient therapeutic relationship⁽¹⁵⁾.

For nurses humor is humanizing, manages emotions, reduces tensions, and improves communication during hospitalization⁽⁷⁾.

Factors that influence the use of humor

Humor is influenced by personal factors such as personality, age and gender characteristics, in which men have a greater ability to use humor than women⁽³⁾.

In another study, it was found that regarding gender, women in situations of illness use humor spontaneously related to the situation they are experiencing and to relativize the situation when speaking to others⁽¹⁵⁾. Men use humor in the form of anecdotes and stories, in order to establish a balanced sense of power between nurse/patient⁽¹⁵⁾.

The circumstantial factors that influence humor are: the level of stress and perceived difficulties; duration of limitations resulting from the disease process; previous experience; ability to use verbal and non-verbal communication strategies; amount of physical symptoms and negative attitudes before illness; disease severity, pain, disability and psychic suffering; liking humor and; ability to perform executive functions⁽³⁾.

Factors that influence the use of humor have been identified and humor is influenced by gender, context, culture, self-esteem and the nurse’s confidence⁽⁷⁾.

Another study was conducted people with chronic kidney disease undergoing hemodialysis⁽²¹⁾ and the factors that influence the appreciation of humorous films by these people were identified. It was found that people with chronic kidney disease who enjoy humorous movies consider themselves to be more cheerful and fun, report having a sense of humor, like to play and laugh, like to be with people who make them laugh and with a sense of humor, enjoy reading comic books and listening to funny anecdotes and stories.

When planning humor intervention, nurses must take these factors into account, not only in the decision to include this intervention in the care plan, but also in its construction and implementation to ensure personalized care.

Activities of the humor intervention

Another study describes the types of humor nurses identify in their practice. Nurses mentioned that humor manifests itself through laughter, smiling, joy, as a state of mind and well-being⁽²⁾.

The strategies and benefits of humor intervention used in the orthopedic service in a Portuguese hospital⁽²²⁾ are play, slap sticking, jokes, anecdotes, puns, surprises, funny situations, personal experiences, comic comments, spontaneous comic expressions, music and movies. Laughter and humor therapy are used by people undergoing hemodialysis in the form of humorous videos, stories, clowns and laughter yoga⁽²³⁾.

Intervention activities can be based on verbal and nonverbal humorous situations, images, photographs, riddles, songs, mental enigmas and riddles, and the construction of a portfolio of funny books and photographs, jokes, comedy films, cartoons, funny news stories and articles⁽³⁾.

In Portugal a doctoral research created the “mobile smile”, which consisted of a car similar to medication cars, which had books, magazines, films and other humorous material that was distributed to people who were hospitalized according to their preferences⁽¹⁾.

These activities are in line with the 15 activities outlined and recommended to implement the humor intervention classified in the NIC⁽⁵⁾.

Benefits of humor in the context of health care

For people experiencing a disease situation, humor brings benefits to the therapeutic interaction, leading to greater collaboration / participation of the sick person⁽⁷⁾. Nurses report that humor is an excellent working tool as it facilitates communication, humanizes care and promotes the therapeutic bond / relationship⁽⁷⁾.

The use of humor in nursing practice has also been a concern in the USA, as in 2008 an article⁽¹⁹⁾ emerges that seeks to evidence the benefits of using humor in a perioperative context. It concludes that humor is used to establish relationships, alleviate anxiety, release anger in a socially acceptable way, avoid or deny painful feelings and is a way to facilitate learning.

In a study conducted in the UK⁽¹⁰⁾, the author advocates using humor in nursing practice as it, helps to develop the therapeutic relationship and building resilience, promotes physical and psychological well-being, and reduces stress and anxiety.

The main indirect benefits of humor are: improving relationships, trust, participation and involvement in care, proximity, motivation, breaking barriers, optimism, good disposition and adherence to treatment. The main direct benefits mentioned were: recovery improvement, stress reduction, relaxation and relief of tension, distraction, pain reduction, exteriorization of feelings, adaptation mechanisms, quality of life improvement, learning facilitator, reduction of anxiety⁽²²⁾.

Another study⁽³⁾ describes the benefits of humor in organizations and health care. It shows that when using humor teams are more productive, cohesive, show less stress and are more motivated and satisfied. In health and people’s life humor promotes well-being; helps to deal with difficult and unpleasant situations, reduces tension, stress and discomfort; increases tolerance to pain, and strengthen the immune system.

Limitations and precautions of humor intervention

Nurse’s perceptions regarding the use of humor in the context of care indicate that humor is something very personal. What makes one person laugh, can cause discomfort and suffering in another⁽⁹⁾. This situation reveals the paradoxical character that humor can have⁽¹⁾, that is, what is motive for humor in one person may not be for another⁽³⁾. In this sense, the use of humor must be appropriate to each situation due to the fact that it is a multifaceted phenomenon⁽¹⁾.

In the UK a study demonstrates that the humor in the medical / patient interaction should be cautiously used, especially with regard to self-deprecating humor. Therefore, nurses must be prudent and use an evidence-based approach during humor intervention⁽²⁴⁾.

Another study identifies barriers to the humor intervention in nursing practice, such as its use in inappropriate situations, the use of humor by a new or junior nurse, the impact of humor on the nurse’s professionalism, personality differences and environmental factors⁽²⁰⁾. These barriers may influence the non-use of humor in nursing practice, as they may associate their use with an inadequate professional practice.

In Spain and Portugal, the importance of using humor in nursing practice has also been investigated. In Spain the applicability of humor in palliative care was studied and it was concluded that it plays an unquestionable role in this context. Nevertheless, its use still requires training and an appropriate use for each situation⁽²⁵⁾.

The articles in Portugal show the use of humor intervention in the practice of nursing care, in different contexts. The humor intervention is complex, since humor is paradoxical, situational, multifaceted and its use must be weighed in some situations, namely in people with cognitive impairment, mental illness and in situations of severe illness. However, when nurses make an appropriate assessment, it seems to have numerous benefits to health and well-being⁽⁶⁾.

Study limitations

The limitations of this study are related to the exclusion of incomplete articles, abstracts and those in languages other than English, French, Portuguese and Spanish. The time horizon may also have limited the research as only articles published in the last 10 years have been included. Finally, all studies were accepted without making a quality appraisal.

Contributions to the sector of nursing, health, or public policies

This scoping review allowed us to retrieve information on humor definition; its applicability as a nursing intervention; humor as a tool to improve nurse-patient communication and relationship; influence factors; type of humor interventions; humor benefits in health care context; and limitations and precautions of humor intervention.

The results of this review may contribute to improve the planning and implementation of humor intervention in nursing care practice. It may give important contributions to the humor intervention described in NIC⁽⁵⁾. On the other hand, it can help in the justification of three NANDA-International⁽²⁶⁾ diagnoses: in terms of promotion, prevention and change of sense of humor.

The synthesis of these results may boost the implementation of humor intervention in the nursing curriculum, since it describes the main indications / applications of humor, factors that influence humor, the most used activities and their benefits, as well as, the precautions to be taken within its use. On the other hand, this systematization may provide clues for future research in the context of nursing care.

The use of the scoping review methodology in this study highlights not only its contribution to the development of qualitative research, but it also evidences the practical implications of using humor as a nursing intervention, in improving the relationship and experience of patients.

CONCLUSIONS

Humor is a subjective emotional response resulting from the recognition and expression of incongruities of a comic or absurd situation.

Humor is humanizing, it allows the bettering of the experience lived in hospital context; it also allows the improvement of the communication and the trust between the nurse and the person during the process of care. On the other hand, it increases the person’s participation in care.

The use of humor favors communication, which plays an important role in human interactions. It helps to promote well-being; dealing with difficult and unpleasant situations, reducing tension, stress and discomfort; increases tolerance to pain, and strengthens the immune system.

It is influenced by internal (personality), external and social factors. However, nurses should use it with caution, since it requires training and individualized strategies.

Humor is a complex nursing intervention, which should be used when appropriate. It deserves caution, training and adaptation to the person and must be integrated into its concrete and singular situation.

Author(s), year, location	Population	Aims	Methods	Results
Bennett et al., 2014, Australia⁽²³⁾.	11 articles about humor on different populations	To identify the evidence related to laughter and humor therapy in people undergoing hemodialysis.	Narrative Review (NR).	Therapeutic interventions range from humorous videos, stories, laugh clowns through shrill simulated laughter and Laughter Yoga. The effect of laughter and humor on depression, anxiety, pain, immunity, fatigue, sleep quality, respiratory function and glucose levels may have applications for the context of dialysis and requires more research.
Branney et al., 2014, United Kingdom ⁽¹⁶⁾.	10 men with penile cancer	To explore how men with penile cancer build humor in relation to their diagnosis and treatment.	Qualitative. Focus group. Nvivo analysis.	Humor helped participants to minimize their condition, which meant they could laugh about the treatment consequences and build a relationship with health professionals. The results suggest a combination of functionalism, relief, and humor incongruity theories. When appropriated, nurses should continue to use humor to build a relationship with people in illness process. Jokes about sexual and urinary function should be avoided.
Buxman, 2008, United States of America ⁽¹⁹⁾.	Articles about the use of humor in the perioperative period	To explore the use of humor in the perioperative context.	NR.	Humor has multiple purposes and offers numerous benefits for both health professionals and patients. In the perioperative context, humor can be used to establish relationships, relieve anxiety, release anger in a socially acceptable way, avoid or deny painful feelings, and facilitate learning. Nurses in this context can use a variety of techniques and resources to increase the use of humor.
Haydon et al., 2015, Australia⁽¹⁵⁾.	4 nurses	To explore the experiences of four nurses on the use of humor in relation to gender differences and how it influences the therapeutic relationship.	Qualitative Narrative inquiry.	The study revealed gender differences on how humor is used by patients. For women, humor is often instantaneous and linked to the situation. It is used to facilitate communication for others. On the other hand men generate humor through stories and anecdotes. This is designed to establish a sense of balanced power between the patient and nurse.
Haydon & Riet, 2014, Australia⁽⁹⁾.	4 nurses	To report the perceptions of four nurses on humor initiated by patients; how nurses react to patient's humor in the clinical setting.	Qualitative. Narrative inquiry.	Humor is a very personal concept. What a person thinks is funny does not necessarily make the other smile, as it may even be painful. Humor is an important communication tool for patients, as it humanizes nursing care, creates a bond and opens communication channels. Humor has the potential to change a patient's experience during hospitalization
Jone & Tanay, 2016, United Kingdom⁽²⁰⁾.	7 articles	To identify studies about nurses' perceptions of potential barriers to the use of humor in practice.	Systematic Literature Review (SLR) Qualitative studies.	The review and thematic analysis identified five key themes: (1) inadequate situations, (2) being a new or junior nurse, (3) impact on nurse professionalism, (4) differences in personality, and (5) environmental factors. Conclusion: the results identified nurses' perceptions about possible barriers that prevent the use of humor in practice. The extent to which nurses use humor is related to personality factors, but it is also affected by external and social factors. The reluctance in its use in practice is influenced by views that humor is not professional; with senior nurses found to have a relevant role in influencing its use.
Liptak et al., 2014, United States of America ⁽¹⁷⁾.	20 people with cognitive impairment	To describe humor and laugh in people with cognitive impairment (PWCI) through a caregiver focus group.	Qualitative.	Humor and laughter were present in all four focus groups. Emerging themes of humor included foolish, sarcasm and comments on the difficulties of dementia.

Five main topics were identified: (1) humor definition, (2) humor use and applicability in palliative care, (3) how to use humor, (4) when does not to use humor, and (5) humor before and after diagnosis of terminal disease. In the palliative care context the function of humor can be classified into three main topics: building relationships, as it improves relations between patient and family, patient and health professionals and between health professionals and families, leading to bonding, developing trust and providing more relaxed relationships, reducing levels of fear and distance between people, strengthening and consolidating therapeutic relationships: it allows the management of conflicts through communication and active listening of health professionals, being a channel to discuss complex issues, such as death, giving information and transmitting bad news; finally, it allows the expression of feelings, recognizing people as human beings and bringing humanity to the health professional. It facilitates the relationship with others, as it helps to foster the understanding of the person, of others and of oneself. The physical benefits from the use of humor are relaxation, pain reduction and it helps to deal with other symptoms. Conclusions: humor plays an unquestionable role in palliative care, but its use requires adequate training and use.
