scrypted-ffm

Five Factor Model Personality Class

This npm package provides an easy-to-use JavaScript class for working with the Five Factor Model (FFM) of human personality. It allows you to create, manipulate, and analyze personality profiles based on the FFM.

Installation

To install the package via npm, run the following command in your project directory:

npm install scrypted-ffm

Usage

To use the `FFM` class in your project, first require it:

const { FFM } = require('scrypted-ffm').Scrypted;

Then, create a new `FFM` object with the specified personality trait values (all trait values must be between 0 and 1.0 inclusive):

const personality = new FFM(openness, conscientiousness, extraversion, agreeableness, neuroticism);

Alternatively, you can create a default "average" personality where all traits are set to 0.5 using the following helper function:

const personality = FFM.createAveragePersonality();

The class provides several functions for working with the FFM object:

Public Functions

• FFM.createAveragePersonality(): Creates a new "Average" FFM object with personality trait values of 0.5 for each of the five traits.

• FFM.calculateLikertScore(value): Calculate the Likert score of a personality trait value on a scale of 1-5.

• personality.describe(): Generates a sentence describing the personality traits of the current FFM object based on the Five Factor model.

• personality.toJSON(): Returns a JSON-compatible object representing the current FFM object with normalized and Likert scores for each trait.

• personality.toString(): Returns a custom string representation of the current FFM object in shorthand format.

Getters and Setters

The FFM class also provides getters and setters for each of the five personality traits:

• personality.openness: Get or set the openness trait value.
• personality.conscientiousness: Get or set the conscientiousness trait value.
• personality.extraversion: Get or set the extraversion trait value.
• personality.agreeableness: Get or set the agreeableness trait value.
• personality.neuroticism: Get or set the neuroticism trait value.

These can be used to access and modify the individual trait values of an FFM object.

Example

const FFM = require('scrypted-ffm');

const personality = new FFM(0.7, 0.5, 0.9, 0.6, 0.3);
console.log(personality.describe());

personality.openness = 0.8;
console.log(personality.toString());
